Hi folks. I just adopted two 1 1/2 year old laying hens. Once I got to know her a little, I realized she had a dirty bottom. After looking up what to do about it, I washed her in warm water with Epsom salt. That got the poopyness off, but now she has a bunch of stuff on the base of her feathers, and has a big zit (I think) on her butt right under her vent. I was wondering if folks think it's s zit/infection, cancer, a cyst, or something else. I d love your opinion of what it is and what you think I should do?
