Edie couldn't walk this morning and she is very thin. She is about 14 weeks old I think. She is housed with three other pullets. I though some poop looked suspect, so I treated their water with Corid (5 days strong dose, 5 days the preventive dose). I couldn't tell who was the sick one because they are not too friendly! I came home from out of town for 3 days and this morning she couldn't get out on her own. I have isolated her, given her some nutri-drench and she has pecked some watered down food No one else seems sick. Any thoughts? Please help. I don't think she will last long.pictures are the poop, when I got her (the welsummer) and now.
