How do chickens get lice and what would I look for? They make their own ground pits for dust baths daily, however, I have noticed them to do what looks like preening themselves. Never thought much of it till I read the help request from lice in one of the threads. After looking at all the emergencies threads, I started thinking of EVERYTHING that could go wrong. And my chickens are about six months old I was told and they haven't laid an egg yet. This doesn't seem right. Anything I should be doing?
