I had a mite problem this past winter that I thought I had taken care of. Today when I went to collect eggs I saw mites in the nest box and they were crawling on the eggs. Currently the eggs are hanging out outdoors. If I just wipe the eggs down are they still safe to eat? I've completely emptied, dusted, and sprayed the coop and I plan to spray the chickens when they go in for the night. Is this a cleanliness issue? I clean my coop weekly, should I be doing it twice a week?
