I have had chickens for about a year now. They never have been let out till here recently in the last few weeks. Since they have been turned out they have looked so much better. Also I have noticed they have had some really runny toxic looking poo , and they poo a lot more now. Is this because of their diet change or should I worry about it being something else? Other than that as I said they look real good,bright red combs, bright eyes, generally very healthy appearance. Its AMAZING what free ranging does for them. Maybe I worry too much?
