Last week, had a bad spell of coccidiosis. Thanks to some fast acting members here, I was pointed in the right direction as far as treatment goes. A few days on the meds, all the chicks are doing great. Now, just 10 minutes ago, I walk out and they are all frisky as can be but one hen. She walks around with her eyes closed. No discharge coming from them. When I pick her up, she opens her eyes but shuts them after a few moments. She appears very tired. As soon as I set her down, she acts if shes very sleepy like she can barely keep her head up, and slowly lowers her head, but when she does, every couple of seconds, her head has a slight jerk to it, almost like she has the hiccups. She reacts to sound and gets up when startled, walks a bit, then settles back down. Any ideas on this?
