So I made a mistake and added a few new hens to my flock without quarantining them. I noticed one of them had a glob of dried poop on its rear. The lady I got them from had 3 chickens smooshed in a small box and I just couldnt leave them however I did not do research on introduction until i already introduced them. My biggest worry in the one hen has clear poop and the glob of poop on her rear and I dont jnow what to do about it. Im new to this and just worried about my established flock as they are already belived pets.
