We're down to two chickens (from four) and one is sick! She's in a dog crate inside with heat and food. I posted elsewhere about her symptoms and will examine her for mites. I'll also get some antibiotics to see if that helps. She can't seem to stand up straight and she wobbles when she walks. Mostly she's in a crouch and she spreads her wings to balance. She breast feathers are all gone and she hasn't laid and egg in months. That was fine just this recent behavior..
