I was taking a good look at my hens/rooster today,,trimming nails ect,,when I saw that my rooster looks like he might have scaley leg mites..I checked everyone else,they look fine. but the rooster was a little scaley looking on his foot,,not on the legs though..so I treated everyone and cleaned out the coop and added DE. 1st time I ever had or saw this,,does anyone know where these mites are transferred from,,like wild birds? and is it common? I was hoping that because he's older that maybe it's normal to have a few scales??
