What have i done wrong????

Can I just mention the risks with candling?.... When you candle the eggs, you should just shine the candler in really quickly, looking for veins from around 7 days,not dark patches or movement as yet, then at around 18 days (or when you prefer to do the final check..just no later than the the day you stop turning) you are looking for the contents to be too dark to see through, with a clearly visible air pocket at the 'blunt end. If you continue to hold the candler against the egg for more than a few seconds, eg waiting to see if you can see movement, you can harm the chick...not to mention the effect of the eggs being out of the incie while you do it.

The purpose of candling is really just to remove the 'clear' infertile eggs, as these have been known to burst, spreading 'bad egg' and bacteria all over remaining eggs, and into the incubator itself.  Frequent checking of the eggs can really have a detrimental effect on the embryos...try to resist the temptation,  twice should be be plenty.

Hope this is useful info for you, it is offered to help you, as the same advice was given to me, and I think it sounds logical, and have abided by it myself since. Good luck 

good luck...happy hatching
