I have a 4 week old chick that I got from someone and I just found out that it has lice. There is buildup around the feather shaft which I've read is lice (is this correct)? And now I am wondering how to treat her. There is one other chicken in the same cage as her and she has a few little bugs on her too. They have a chicken feeder and waterer in their cage with them that they have access to all the time. They are both eating and drinking well. I am just wondering how to treat this. I've read about DE but most people say it only helps prevent, it doesn't treat. So I need to know what will get rid of them on the girls. There are bugs crawling and eggs on them. Please let me know what to do to help them. Thanks so much!
