I have tried very hard to find out how to determine if my chickens have mites or lice. They are pecking themselves, mostly at night, but I also see it during the day. I've checked them over and see no sign of skin irritation, nothing around the vents or other places. I don't think I'm seeing anything at the base of the feathers. I have seen (on myself and on a broody hen's eggs) very small black/grey critters. I felt the little creepy things on my head one night after checking the chickens after dark, and after holding a hen. I noticed a few very tiny little things on my pillow, and they didn't fly, could easily be squished. I see nothing red glowing in the dark. Can someone tell me what that is? I've been using DE on the chickens and in the shavings, but think I need to go a step further, but don't know what treatment to use until I know what I'm dealing with. Pictures on the internet tend to be magnified, and there are parts on those magnified creatures that I'm not seeing on these miniscule little specks, so the pictures I've seen so far aren't helping me identify them. And anyone help?
