I was wondering why chicks may not develop all the way? I gave chicken eggs to my son's class for hatching, some hatched 3 days early and today is the 21 day and no peeps on any of the others that are in a different incubator than the ones that have hatched. The teacher said it looked like some had stopped growing a week or so ago, How long do you give the eggs to hatch? No noise and minimal movement at this time...looking for some education on the subject!
3 days early is pretty early. I would say give them till at least day 23 befor candleing or what not . Good luck
At least give it until day 24 or 25. Maybe some weren't fertile or had bad air cells? I don't know if we ever get all the answers when we incubate. Could be humidity also.
