We have a 3 mo. old hen, seven 3 wk old chicks, and four 1 wk old chicks. When we hold the 1 wk old chicks I am seeing tiny little bugs on them - mites? Do I need to do anything about this? We keep the older chicks out in the run with the older hen during the day and bring them in at night. I have not seen mites on them, but I also have not seen the hen or any of the chicks taking dust baths. I put a large feed pan of sandy dirt in the coop today (it's been very rainy and there's not a lot of "dust" dirt in the run right now). We saw the hen in the dust a little but not the chicks. Are these mites something that I need to worry about since we have the chicks in our house in a brooder (a large box w/ shavings, water, food). I don't want any of the 7 of us humans to get mites - can that happen??
