I've been searching info on pasty butt, most of which refers to the condition in young chicks. Is it reasonable to find the problem with an older hen? We've had our BO hen a year, and she's probably 2-2 1/2 years old. She's been quiet the past few days, but then today I saw her hunched over, feathers fluffed, and I noticed her backside was covered in a dark, crusty, awfully smelly hard poo. Her breast bone is sharp as though she has lost weight (not noticed because of fluffed feathers), but her crop feels soft. Her comb has always been flopped over, but now it's pinkish instead of the red it normally is. I've clipped and cleaned the poo mess around her vent; she was quiet and didn't fuss at all, probably glad to get it cleaned. She's isolated in a large dog crate with straw bedding, water with a T of vinegar, and a small saucer of plain yogurt along with her regular mash. Am I on the right track or should I be doing anything different? Thanks for all suggestions here. Of course, she's a sweet hen, and I hope to help her mend. ~G
