Hi one of my chickens died yesterday and buried her this morning:,( she had a very poopy hind end. She seemed to not have any strength in her body and couldn’t or wouldn’t move. She’s a LH and has always been weak and stopped laying eggs about a month ago. I didn’t see any white or yellow on her tail feathers but it was MATTED with dried poop. Can some one please shed some light on this and help me protect the rest of my flock.
