One of my new hens has a bare butt, i didnt notice it when i got her unfortunately- my fault. She is very skittish so I'm having a hard time grabbing her even at night.i follow her around and her butt is totally bare when she moves her feathers to poop. It looks smooth and a slight bit red/pink. No signs of flies or parasites but i realy need to grab her to totally check her out. I have vericyclin and other meds. How can i grab her without freaking her out even more as i need to treat her. She is eating fine and poops are solid. All hens were dewormed twice already too She has great energy too and walks fine around the yard etc. she has a little bit of dried poop sticking to her feathers also.
