Please help me . I'mm new to chikens, 6weeks, I have aquired 2, 5-6 year old hens. I just love them. A few days ago I noticed that one has messy butt. This am when I let them out there was a large spot under her perch, bright red and not mixed with poo. She came out and was eating and doing her usual routine. There also seem to be lice ? around her vent. They are not easy to catch so I will have to check her tonite when she roosts.
