I just went down to the coop to check on my broody hen (babies due to hatch tomorrow!) and I noticed the new box I have her in with clean pine shavings, etc seems to be infested with tiny (size of a pin head) bugs, lice or? What should I use to rid her of the parasites that won't harm the babies? Is it safe to move her and her nest while I do this? Thank you for your help.
