I lost one bird last night and there were 2 more acting strange and exhibiting similar symptoms tonight so I took them out and isolated them from the rest of the flock. The one that died last night had his head turned backwards and he couldn't stand. He was flopping on his back like a fish and wouldn't eat or drink. The ones tonight seemed very tired and kept running into walls and the one was starting to lose his balance and the other looks like it went blind in one eye. I'm afraid I'm going to lose the whole flock. Any help would be greatly appreciated!
