Hello! I'm new here, and new to raising chickens. I live in Michigan. Everything has been going quite well the past two months since taking in these 8 beautiful girls. Until this morning. I went out to great my girls this morning and found one of my girls is lethargic, weak, labored breathing, and not acting right! She is eating. Her color is slightly pale, but, pink. I've felt her all over and she feels warm and good, even looks good other than acting off. There is no sinus drainage, no wheezing, not pasty butt, no lumpy gut, no lumpy neck. Giving pro-biotic and electrolyte water treatments. Not sure what to do next. I can bring her to the garage in a hutch to quarantine. Not sure if that is enough, or should she come inside? Don't want to shock her with the vast temperature change (it's winter here). Any guidance would be appreciated. I've been reading blogs all morning. So worried I wanna cry!
