One of my Buff Orpingtons seems to be coming down with something. Looks like the other girls are pecking on her and perhaps pulling feathers out. She is now totally lethargic, staggers around when she tries to walk and cannot get up on the roost. She's been sleeping in one of the lower nesting boxes that is on the floor level. I'm thinking of putting her in a dog crate with some shavings a water and bring her inside. All the other girls are out roaming in the yard and this one is nestled down in the grass.
