Is this true....someone told me I could transmit mites to my coop, if I recieved a bird that has mites, he was treated before he left, and i dusted him when i got him, and he is in. my mud room away from the other birds, i havent seen any on him and will be trating him again on Wednesday.
Yes they can. Mites can come into you coop with wild birds too.
I use mite strips on my coops from McMurray Hatchery.
