I hatch a lot of chicks. Had 50 hatch this weekend. Every once in a while I will get a chick and they usually are the large ones that gets stuck in their shell, I help them out and then they paddle their feet and flap their mini wings, but never stand up. They can muddle around the floor of the brooder and to date they have all died. Probably can't get food and water properly. Does anyone else have this happen? Do you know what it is caused from? One guess it that they get so big in the shell that maybe their legs break or become deformed? Thanks for any ideas.
