I have a hen sitting on eggs and up until a couple of days ago, she would go out and dust bathe. Today she had her first chick! However, when I put my hand under her to look, my hand came back out with what I assume are mites. I been gently checking under each day and this is the first time I've seen this, but there now seems to be a lot. Is there anything I can do. Like I said, she has one chick now and I saw evidence another is making it's way (a pip?) soon. Thanks!
