As I have been battling mites for a couple of weeks, I have been reading threads about the little demons. As that most are older threads, I haven't gotten any responses from my posts. So here is hoping for some advice and help with this thread. About a month ago, we had a huge snow storm with 12 - 18" of snow that kept the ground covered for a week. My flock did not dare venture outside for any of that time - the Prima Donnas! That's when the problems began. I have used permitherin powder on my girls liberally about 4x in the last month. This did not seem to be fixing the problem, so after reading another thread, I decided to try Ivomec. The flock appeared to look better (redder combs, wattles, etc.) for a day or two. Now, I'm seeing pale combs, redness on the legs of one of my roosters (don't know if this is in relation to the mite issue or not), and one hen's middle toe is swollen on both feet and I think she lost the toenail. I've changed the nest box material twice and treated with permitherin powder. One of my biggest concerns is that I have sand for the bedding of my coop (a truck bed load to be exact). I understand that I need to spray my coop, but do I need to remove all of that sand before doing so? I chose sand because I thought it would be cleaner, but now I am worrying that the little buggers are burying down and hiding in it My vet has suggested using something called Atroban to spray my chickens and the coop. Has anyone used this and if so, did you have any luck? I've mixed cedar shavings in with the sand. I've bought the DE and seven dust. I've also built a nice fire the last couple of days so I will have some wood ash. I would set off smoke bombs in the coop, but with all of the ventilation, I don't think it would be worth the time or money. I just want the little demons gone now!!!! I am willing to empty the sand if necessary and hand dunk every chicken I have (27),but if I get rid of the sand, what do you put down in it's place that's any better??? Also, while reading another post, I got very concerned. I cleaned out the litter of my coop last weekend (like a huge cat little box) and put the waste material in my garden area. (whole point of coop being built next to garden - natural fertilizer). Yes, it had some feather shafts in it - so now is my garden going to be infested? Any and all advice is greatly appreciated. Thank you to all who have already posted about mites. I'm trying to learn all I can as that I'm a relatively novice chicken owner.
