My elderly lady has a big old poopy butt. Always. I catch her and wash her off, but the next day it is back. I had to work these past few days, so I did not have time to chase her and wash her and she had a massive poopy butt- like a tennis ball hanging there. Not ON her vent, but under, on her butt feathers. She has not layed in ages, she is obviously old. All my other ladies are fine. Very well groomed, in fact. Time to send her to the big henhouse in the sky? Yes or no?
