So I got two new chickens last weekend and both act normal but the rooster looks like he has raised scales. He has just a tiny bit of feathering (i think) on one leg so maybe it's just from where he used to have feathers but he plucked them out idk. If he does have scaly leg mites then I definitely don't want it spreading to my old flock right now him and his hen are separated but they're in a pen that has lots of straw which i want to use later for broody hens. How can I get the mites out of the pen? Here are some pictures of his legs (which he put up quite a struggle for me to get them ).
