Help! My girls have mites and I am just some kind of dumb! I'm still very new to chickens and have no clue how to treat them. I reached in to get eggs today and got more than I bargained for. On my way back to the house, I felt something crawling on my arm. I looked and found a TON of light brown mites crawling. They were all over the eggs, too. DH bought Sevin dust, but someone else said diatomaceus (?)earth. Either way, how to treat is my problem. Also, since they free-range, is my yard now a risk to the kiddos?!?! ACK! Freaked out, here!!
