Hi, i had a hen die a couple weeks ago from i dont know what, she was very sick, weak, bad diareah sticking to her bottom, her legs would go stiff and she would just lay on the ground, no feathers on her neck, and she was losing alot of balance! I tried giving her corrid for 3 days, but on the 3rd day i found her dead. I never figured out what was wrong with her. Anyways, today i noticed one of my rhode island reds start to lose feathers on her chest/neck area just like my sexlink that passed, and she isnt eating as much, she just kinda sticks to herself. And her poo is starting to stick to her bottomfeathers a little now. What could this be? Ive heard people say lice or mites, and others say it could be cocci, or some other disease. Please help me. I dont wanna lose another hen, they are my babies.
