I'm new to owning chickens and need some advice. My sister in law bought my daughter two polish frizzles for her birthday and within the first month we lost one of them. She was acting sleepy and not herself the day before she passed. Now my other polish frizzle is acting the same way and we started them on corid and non medicated food. He has runny poop with mucus and I have seen blood in it before. He is laying down a lot with his head tuck into his body, feather are ruffled and seems like one of his wings he can't really move. He was trying to get on his roosting stick and seems off balance. He is drinking water on his own although I have not seen him eat he has been by the food. This morning I noticed his head kind of ticking back and forth but hasn't since. I'm not sure what to do. I thought it was the cocci since my new puppy had to be treated for it a month or two ago. My other hen is doing fine she is acting normal and eating and drinking fine. Although she is being treated as well with the corid. Any advice would help thank yall!
