I think we have mites. My old english game bantam hen had a clogged butt, so I brought her in to clean her up. While I was holding her, I noticed some VERY SMALL brownish bugs crawling on my hands. There were only about 5 of the bugs. I couldn't find any bugs on my hen. Do we have mites? We picked up some Sevin just in case. After dusting, is it safe to eat the eggs?
