As of now I have lost 5 chickens all in the same way and I can't figure out why! The night before they seem sleepy and slow and they find it hard to jump up the step into the coop, I end up having to pick then up and put them in. Today 2 of them where all huddled up with they're eyes closed and didn't move too often. Their wings are shrugged down to their side and they can't pick they back up. They also seem really off balance and find it hard to stay up if they get pushed around. And then they just die. I don't know if this is a disease or they can't handle to cold weather like they could before or what. Please help!
