This is my first flock so I'm not sure what's going on. I got my first 6 chicks that hatched in April. My NH Red has had a yucky butt starting when they began free ranging all over the yard. I've tried deworming using pumpkin seeds.......NOTHING. I've also done probiotics in their water for yeast........NOTHING. None of the others have this issue and they've all been together since I got them. Just curious what I should do next? She is saying randomly and I believe she thinks she'd a rooster mounting half of the girls. What should I do next? Thanks in advance. Here's a poop pic!
