Hey guys...I noticed when my 3 week old cochin raised his wing that a very small reddish brown bug ran across his armpit. I also noticed his poor lil skin on his back was red last night when I went to put then to bed. Is that mites? I called my local feed store & he said he had Poultry Protector...is that what I need? How do I treat the coop area and we are finidhing the run this weekend, so do I need to do anything with the sand we will be putting in? Thanks!!
