One of my hens never developed fluted upright tail feathers, hers are rounded, around her body. Therefore she constantly has a poopy bottom. I rinse her off a couple times a week but this is getting old. Has anyone ever had a hen like this. The guy at the feed store told me they will grow out, this was when she was a chick, but now she is 6 mos.old and nothing. She is healthy and a good layer but I can't stand that poopy bottom and she smells all the time can I cut off all her feathers around her vent? Thank you for your suggestions. New at this but learning and loving it.
