As I was scraping poop boards today, I noticed a few crawlies. They were little tiny ants, I think. Then I noticed my roo seemed to be a bit itchy, so I checked him out and found a few mites on him. I have been dreading the possibility of mites with my babies (I have a flock of 10 chicks who are 16 weeks old), so I've dusted with DE every couple of weeks. Seems like that didn't work. I noticed a couple of mites on a few of the other birds that I was able to catch. So, here are my questions. If I choose to go the Sevin route, will that kill ants too? I've read about all the non-Sevin options like citrus oil and DE and cedar...do those things really work? I'd rather stay away from chemicals, but I am not averse to using them when necessary. I'll empty and thoroughly clean the coop, but my run is covered in sand, and part of the run is covered by a raised coop. The underneath part is rather hard to get to. Do I need to empty out all the sand and replace it? Does having mites indicate that my coop hygiene is sub par? I scrape poop boards every 3 days or more often when needed. We do the deep litter method and I add new shavings and DE every 1-2 weeks. Just last week my son and I did a pretty thorough scrub of all the dust and dried poop. There are an awful lot of feathers in there--do I need to collect those regularly? My chickens free range on our 3 acre yard during the day, if that makes any difference to anything. The thought of bugs on my chicks grosses me out to no end. bleh!
