I have a hen today that was hiding in a corner of the barn, panting and has black poop. Now yesterday I had to catch a few peachicks and the ducks were avoiding me in a pure panic. One of them got stuck in the fence. This could be her. They all look the same, so beats me. No visible external injuries. I'm giving her a soak in the bath just in case. Any ideas? Could it just be the panic of yesterday?
