I think you make a few good points, but you come on a little strong. This woman obviously loves her pet chicken, and is trying anything she can to help her. Everyone does things a different way.This chicken is very sick, you have done everything possible and from what I know, all the right things. But there is a point where a sick chicken must be killed. From what you describe as the symptoms it sounds serious. Do not endanger your other chickens by keeping this one around. Even if well-separated, you are going in and out of both locations and YOU could be spreading the disease on your boots, clothes, hands. A quick and painless death is required for your poor sick girl. Buck up, this is part of the process. - Lorna at Fowlty Towers Egg Emporium
