sac

My chicken has this sac on her head that feels as if there was air or water in it. It does not feel like a tumor and is slightly squishable. It's almost as big as a quarter in diameter and doesn't seem to be bothering her (still lays eggs and behaves normally), so is this something I should be...

Hey everyone. We had 3 chicks hatch on Tuesday from an incubator. One had a bit of shell stuck to its back and wing. A bit like a hunchbacked tortoise. It’s weaker and smaller than the other 2 chicks so I am trying to nurse it back to health. These are my fathers hobby but I do all the sad...

This is my first time hatching and something like this happening. I've searched online and not sure what to do. When the chick came out it had poop at the end of the sac and it look to be attached to the egg as well. It looks like it's coming out of the cloaca, should I try pushing it back inside?
