I've looked at her bottom....way below the vent....and it looks raw and irritated.....feathers broken like she's trying to get them out. She was standing in the pond yesterday, as if the water was cooling her off. NONE of the hens have ever gone in the water. She's eating and drinking and going about scratching and schooling the small chicks, but her bum doesn't look comfortable. I checked closely for mites, lice, prolapse (can't miss that) or anything for a clue. Got any ideas? Thanks, you're all so good at detective work!!!
