Difficulty hatching?

My chicks have been trying to hatch since Thurs evening when they broke the shells on their eggs, but the chicks are still not out? They are alive still but is it normal for them to take that long to hatch?

I havent had this problem before until this week where the same thing has happened (Wyandotte Bantams)
The membrane seems really thick compared to what i've hatched in the past but they eventually managed it and they all came out really soggy this time ( i was worried about them drying out)

When i hatched some quail earlier this year, that was a very slow job, some were taking 48 hours but they all hatched.

I increase the humidity in the last couple of days too ( i just follow the instructions with the incubator)
I'm not one for tampering with them whilst hatching but you must do what feels right for you

Well done
Having something none slip under them helps.........rubber matting,kitchen roll or and old tea towel

I had the exact same too like you and splash101. I had to get a dampened sponge after 48 hours or so from pipping and wet the membrane as it had dried and seemed very thickened on 2 of the eggs (I watched how to do it on you tube lol!). It was really good for us - (kids too!!) to see how they come out (eggs under broody) after releasing them just that little bit allowing them to come out the rest of the way themselves, voila! I remain certain that I would have lost those two from exhaustion had I had not given nature a little helping hand  I have been told mother hens help their chick come out if needs be but I'm not so sure as she wasn't doing anything but?? I wonder if hatching small eggs under such a big fluffy warm old girl was partly the problem and it caused them to dry faster again who knows?! Good luch with yours x
