A couple of weeks ago I had a hen that needed to be put down because her belly skin had dried up, cracked open and then the belly underneath was like full of liquid. We thought maybe it was because she was really old. But now I have a hen who isn't even 2 yrs old that is displaying the same behavior and when I checked her belly.....sure enough....it was featherless and her belly is full and mushy! Please help. I need to know if there's a disease spreading throughout my flock! I only have a few chickens, but I don't want the other ones to get this. Or if I get more chickens later, I don't want there to be a disease in the coop that needs to be taken care of!!! Thanks for any help!
