I was just down at the coop holding my sweet little NN pullet and there was a tiny little thing crawling on her neck and then I had seen another on my hand. It was very tiny and maybe like a light brownish type color. I also now have the feeling of creepy carwlies all over me!!!! I have a few questions concerning treatment. What is the best way to treat them? I have seen different options in searching but not sure which to use. Do you HAVE to take out all of the old bedding? They have a very large area in the barn and I am doing the deep layer method and there is tons of bedding in there. Lots of time & money to replace all of it. I have been adding DE to the coop weekly and additional bedding as needed. Would there be anything I could dust in the existing bedding? Will I basically have to treat the entire barn because they do run about outside as well as in the barn? I have 22 pullets, 2 Orp young hens, 4 silkies roos and recently added 2 new silkie girls that are laying and one is broody & sitting on eggs. I know I have asked alot of questions but I would like to treat them asap and want to be sure it is effective as well as safe especially for the broody hen & eggs! I wanted to add that no one appears sick or not growing or gaining weight. They are all eating & drinking and acting fine.
