When I went out to let my chickens out of their coop this morning, one was really slow coming out. I went over to him & realized his eyes were shut. I thought he was just waking up, but then when he wouldn't open them at all I knew something was wrong. I immediately took him to a small cage in my garage and he just huddled up in the corner (head drooping slightly). I went back out to take a look at my other birds and noticed 3 others in a similiar (not quite as bad) state. I brought them all inside and put them together (I don't have a lot of room to separate them). Their poop shows no sign of blood. I put antibiotic in their water, but they're not drinking it b/c they won't open their eyes! I tried using a dropper, but that didn't really work...I couldn't get them to open their beaks. I dipped their beaks in the water, but not sure that they really got enough to make a difference. Any advice would be helpful...(other 6 chickens seemed to be fine this evening when I locked them up for the night). I treated their waterer in the coop w/ antibiotic, so hopefully they were drinking during the day.
