The chicks start shaking the egg and chirping then it stops. When this happened I thought that it was just them getting tired and taking a break. But after three days none of the eggs hatched it was day 25 so I decided to crack open an egg and see what was up. When I cracked it open there was a thick skin thingy over the chick, to make sure that it wasnt just the one so I cracked two more but both of them had the same exact thing.
I am thinking that the skin is to thick for them to get through so they are dying.
What could have caused this to happen.
The membrane gets really tough to fight through if it was too dry
