Lily is a Black Austrolorp who is about 9yrs old. In the last week or so, she's started walking funny, almost waddling, and she's been acting way slower than usual, but she hasn't lost any weight. This morning she was worse, and although I have a heat lamp in my coop due to the recent cold, I brought her inside and got her warm. None of the other birds in my flock are showing any symptoms. She isn't bleeding either, nor does she have any injuries that I can see. She was getting a little more attention then usual from the boys last week, but not within the last several days. She hasn't been eating a lot lately, but she has been drinking, and I've been putting electrolytes in the water too. Her poop is kind of like guacamole, mostly just green and thick-ish. I'll post pictures of her as soon as I get the chance. Thank you in advance!
