We got several chickens/chicks last month. They are now almost 2mos old. Yesterday I noticed one of the Americanas wasn't looking right. First day I'd noticed this. She wasn't moving alot and her wings were down. So I moved her out of the "adult" area of the coop(hoping she was just being picked on) and in with some chicks we have that are a couple weeks old. Well, this morning she was dead. Then my husband told me that one of our Freedom Rangers was dead today when he got home(in "adult" part of the coop as well). I didn't notice anything at all this morning when I went out there. Now I'm worried that something's wrong with all of our chickens and that we're gonna lose more. What could this be?? Any help or suggestions for me??
