I have just discovered that I have mites. Er, well, my chickens have them. I have just one hen with scaly skin all over her legs. The rest seem fine. I realize now she has been like that for a few weeks. (bad chicken momma, I thought it was just dry skin or something) I am going to vasaline her legs in the am. I would like to dust the chickens, what do I dust with? I will do them all. I understand that the coop should be treated too, but is there any way to not do that? I can't keep them out of the coop for any more than a few hours while there is daylight. (7 to 5) so i dont know how I would treat it and allow them to go back in without doing any harm. hmm... But most importantly, what is this dust that people use?
