So I got a new silkie cochin mix today. It was from a friend. My son said he saw a bug crawling on the bird and that there were bugs on him after holding her. Sure enough I had them on me too. They are very small and somewhat reddish brown. I am new to all this chicken stuff. My friend did not know about the problem and was going to go home and check her other chickens. I have tried to rub in some DE on the outside of the bird. I have dusted the outside area and brooder for the chicken. I am worried my other chicks(4 week olds) will get it too or maybe it is not such a big deal? Does it sound like mites? Are they a big problem?
