Title: Development of the chick - candling pics (day 1-21) video of hatching!
Post by: Casey76 on March 27, 2011, 21:26
I hope that this thread will be interesting and useful to everyone :)

On Saturday 26th March I set 8 porcelain Sabelpoot eggs from my pair of porceialin sabelpoots.  The eggs were laid over 11 days, and they are all dated on the egg.  So far I have 100% fertility in my other Sabelpoot eggs I've set so far.

The eggs are very nice (even if I do say so myself ;) ), they are even in shape and size.  The shell is not overly porus, the shells do not have wrinkles, or calcium deposits.

Day 1:
(http://i4.photobucket.com/albums/y108/oconnka4/Chickens/Chook%202011/Day1b.jpg)

(http://i4.photobucket.com/albums/y108/oconnka4/Chickens/Chook%202011/Day1.jpg)

Nothing to see yet, and the air cell is still very small, near the light.  In the second pic, the slightly darker shadow which can be seen is the egg yolk.

Day 2
(http://i4.photobucket.com/albums/y108/oconnka4/Chickens/Chook%202011/day2b.jpg)

(http://i4.photobucket.com/albums/y108/oconnka4/Chickens/Chook%202011/day2.jpg)

Again, not much to see at this stage. The aircell is still too small to be seen (though as they are sabelpoot eggs, it will remain small :)

Day 3:
(http://i4.photobucket.com/albums/y108/oconnka4/Chickens/Chook%202011/day3.jpg)

(http://i4.photobucket.com/albums/y108/oconnka4/Chickens/Chook%202011/day3b.jpg)

and in case you can't make it out very well...
(http://i4.photobucket.com/albums/y108/oconnka4/Chickens/Chook%202011/day3benhanced.jpg)

We have life!

How big is the difference between day 2 and day 3?  Already the embryo is starting to grow a visible network of veins :)

Day 4
(http://i4.photobucket.com/albums/y108/oconnka4/Chickens/Chook%202011/day4.jpg)

(http://i4.photobucket.com/albums/y108/oconnka4/Chickens/Chook%202011/day4b.jpg)

and again with the outline on:
(http://i4.photobucket.com/albums/y108/oconnka4/Chickens/Chook%202011/day4benhanced.jpg)

Things are really cooking now ;) you can see how much the network of veins has grown in 24 hours, and how much  bigger the actual embryo is (this is the circle in the middle of the spiderweb of veins).

What I think is especially amazing, that even though these are two different eggs, the pattern of veins is almost identical!

Day 5:
(http://i4.photobucket.com/albums/y108/oconnka4/Chickens/Chook%202011/day5.jpg)

(http://i4.photobucket.com/albums/y108/oconnka4/Chickens/Chook%202011/day5b.jpg)

(http://i4.photobucket.com/albums/y108/oconnka4/Chickens/Chook%202011/day5benhanced.jpg)

By now the embryo has completely surrounded itself in a blood island.  If you look closely you can see the heart beating, and the black dot of the eye is clearly visible.

Day 6
(http://i4.photobucket.com/albums/y108/oconnka4/Chickens/Chook%202011/Day6.jpg)

(http://i4.photobucket.com/albums/y108/oconnka4/Chickens/Chook%202011/Day6b.jpg)

Day 7
(http://i4.photobucket.com/albums/y108/oconnka4/Chickens/Chook%202011/day7.jpg)

Video of heart beat (click!)
(http://i4.photobucket.com/albums/y108/oconnka4/Chickens/Chook%202011/th_P4020317.jpg) (http://s4.photobucket.com/albums/y108/oconnka4/Chickens/Chook%202011/?action=view&current=P4020317.mp4)

Many people do a preliminary candle at day 7 to test for fertility... all my eggs are fertile ;)
We have now gone past the spider of veins and now the embroy is forming at a very rapid rate.  In the video you can see it swishig about as the force of the heart beat makes the whole embryo move.

Day 8
(http://i4.photobucket.com/albums/y108/oconnka4/Chickens/Chook%202011/Day8.jpg)

(http://i4.photobucket.com/albums/y108/oconnka4/Chickens/Chook%202011/Day8enhanced.jpg)

Day 9
(http://i4.photobucket.com/albums/y108/oconnka4/Chickens/Chook%202011/Day9.jpg)

Day 10
(http://i4.photobucket.com/albums/y108/oconnka4/Chickens/Chook%202011/Day10.jpg)

I recommend candling on day 10.  At this point is it usually very clear if the egg is fertile and growing.  If the egg was not fertile, it would look like a day 1 egg, perhaps with a bigger air cell.

Day 11
(http://i4.photobucket.com/albums/y108/oconnka4/Chickens/Chook%202011/Day11.jpg)

So here we are at the half way point.  You can see how big the embryo is getting.  From here to day 18, it becomes more and more difficult to see more than a dark area iin the egg.

Sorry for the delay, photobucket was being very tempremental for me :(

Day 12
(http://i4.photobucket.com/albums/y108/oconnka4/Chickens/Chook%202011/day12.jpg)

With a bit of adjustment you can see a little more - just
(http://i4.photobucket.com/albums/y108/oconnka4/Chickens/Chook%202011/day12enhanced.jpg)

Day 13, and things get very dark from now on...

(http://i4.photobucket.com/albums/y108/oconnka4/Chickens/Chook%202011/Day13.jpg)

(http://i4.photobucket.com/albums/y108/oconnka4/Chickens/Chook%202011/Day13enhanced.jpg)

Day 14
(http://i4.photobucket.com/albums/y108/oconnka4/Chickens/Chook%202011/Day14.jpg)

Even enhancing doesn't have too much of effect...
(http://i4.photobucket.com/albums/y108/oconnka4/Chickens/Chook%202011/Day14enhanced.jpg)

Day 15
(http://i4.photobucket.com/albums/y108/oconnka4/Chickens/Chook%202011/Day15.jpg)

(http://i4.photobucket.com/albums/y108/oconnka4/Chickens/Chook%202011/Day15enhanced.jpg)

Day 16 - thes eggs are just sooo full now... not long till lock down!
(http://i4.photobucket.com/albums/y108/oconnka4/Chickens/Chook%202011/Day16.jpg)

(http://i4.photobucket.com/albums/y108/oconnka4/Chickens/Chook%202011/Day16enhanced.jpg)

Day 17
(http://i4.photobucket.com/albums/y108/oconnka4/Chickens/Chook%202011/day17.jpg)

Day 18
(http://i4.photobucket.com/albums/y108/oconnka4/Chickens/Chook%202011/day18.jpg)

Day 20:

Fantastic pictures. Casey, in what you have outlined, am I right in thinking that is the shape of the chick developing i.e. head, abdomen & wings?

Its really interesting and only going to get more so!

Do you use a proper candling torch or what?
Title: Re: Development of the chick during incubation - candling pics (day 1 - 7 visible)
Post by: Casey76 on April 02, 2011, 21:40
I use a hi lume torch from ebay (cost about 8) and a rubber "hood" which is from a proper candler (but the candler is so poor you can't see very much at all)

Post by: hillfooter on April 03, 2011, 10:12
Here's how to make a candler using a hi power torch (Maglite).  The trick is to seal the light arround the shell so NO light creeps round the outside of the shell and obscures the interior.  I used some black inner tube rubber to make the light seal and snipped little 2mm cuts around it very carefully using nail sissors so it was veryflexible.  The light must light up the interior through the shell, don't make the hole too big.

The photo's are great Casey.  I've many times thought to myself I must do exactly what you are now doing but I haven't had the presence of mind to remember my camera so it's very good to see your photos in daily detail.  I only candled at such regular intervals during my first couple of incubations to get a feel for now they develop.  I only now candle twice after 7 days, to reject infertile ones, and 14 days to weed out any which haven't developed.  After that I just let them run to hatch.  It's amazing to see how much they can swirl about in the shell after around 7 days.

This post will be a great help to beginners to give them a feel for how their eggs are developing.   Well done.

Hi HF, Normally I would only candle at day 10 and day 18, so this is something of an education to me too.  I'm just amazed at how quickly the embryo grows!

I hope that everyone will be able to see on the day 10 pics (when photobucket decides to co-operate again) the legs, and even beak on the embryo!

Thanks for the rubber seal idea on the torch HF!  I always get a chink of light when I do mine!

snipping about 1 mm slits or so very carefully around the edge of the light seal with a sharp pair of nail sissors (i used my swiss army knife sissors) makes the edge very flexible so cutting out the light creep.  The black carpet tape helps too.

Title: Re: Development of the chick - candling pics (day 1-21) video of hatching!
Post by: Casey76 on April 23, 2011, 10:36
Which do you mean by "original hatching"?

Last year out of 6 bought eggs I hatched two pullets, both seen on the photo on the last page.  I bought the cockerel in.

This year I've had three hatchings, all about a week apart, with the oldest being 4 weeks old now.  They are still too young for me to be able to tell... however I'm guessing they are both pullets (now comb development yet) :D

It is lovely to see them start to interact even straight from the egg when the others give a curious peck.

Thanks for the pics & info.
Since I have had my Bantams, from three months, I have been watching my rooster go about his business, & hopefully he will add to the flock, I have been candelling some of the eggs, in the hope.
Over this weekend, one of my hens has been on the nest more than usual,which has led me to think that she is about to produce, offspring. This morning, she came out with the rest, apparently very hungry, I took the opportunity to candle the egg she had laid,  I am pretty sure, it has the required tell tale signs of growth , as I rotated the egg, a darker spot appeared, and moved inside the egg.
After reading all the advice on incubating eggs I quickly returned the egg to the coop,  she was already back on the nest, I gently placed the egg back beneath her. If she stays on the nest, I am reasonably certain that she will produce,
Should I put any food or water in the coop, to help her ??????.

any advice would be very helpful, Thanks
Rocker
any advice would help please

Post by: ANHBUC on March 27, 2012, 10:21
No need for food and water in the coop, she will come out for a feed drink and poo.  You don't want her to soil her nest or spill water which will make it damp.

If she is sharing a coop you would be better putting her on her own in a broody coop.  I have 2 broody bantams at the moment.  Each has 6 eggs and I have separated them, one in a coop with run attached and the other I have bought a large secondhand rabbit hutch.  This stops them trying to steal each others eggs which can result in breakages.

Good luck with your hatching.   :)

This evening one of the eggs had like bubbles of hard stuff on the shell, i had a quick look in the egg by candling and it looks like it is full of crystals. I had to wash the eggs off using the disinfectant  (as they were heavily soiled) that came with the incubator and  the instructions said that you had to fill one of the pots up with the disinfectant and not water. I wonder if this has affected the aggs?

That is a really clear one.  Candled some eggs yesterday and one had stopped developing so I opened it to see what stage it got to, about day 14.  Don't know what went wrong but the broody had pushed the egg to the edge of the nest and it was cold.  She still has 2 that I am hopeful for but not sure what date she started sitting.  Will leave her to decide for herself if they are viable or not.
