I am new to chickens. I have a Cornish hen. 3.5 months old. She was fine yesterday morning and was sick by night. I am not sure if her comb was pecked or is turning in color. we have a total of 13 chickens. no other chicken is showing any signs right now. I have separated her from the rest. She is eating and drinking thankfully. Her legs are not working to well if at all. Her poo is green and watery. no chance of frost bite I live in Arizona. been 90+ degrees. Hoping she makes it. Will try to add picture as well.
