I have 2 white silkys that were given to me. i don't know much about chickens but I'm trying to learn as fast as i can. i read chickens in your backyard and i fingered out they have scaly mites the male is so bad his lags look deformed. I don't won't to kill them because my husband will probably not let me get more if these don't work out. last night i put Vaseline on the legs and noticed lice eggs all over the birds. we don't have mush of a feed store around hear but i think somewhere their is an Amish owned one if i can find it.
