I gave a friend one of my hens about a month ago and she just called me today saying something was wrong. When I got there I noticed that she won't put any weight on one of her legs and she looks really lethargic. My friend told me she'd been doing that for a few days, thanks for telling me sooner! I used a dropper to get some water in her and now that I have her back home she did eat a little and try to move around but I am really worried. I checked out her feet, leg, wing etc. and can't find anything obvious. Any ideas?
