I know there are a LOT of posts about mites, but I didn't have time to read through all of them to find answers to my questions. Here goes: 1) Are mites that are on the chcikens' bodies the same as scaly leg mites? 2) Is it o.k. to eat the eggs of chickens you have dusted with poultry dust? (I also sprinkled a bit in the nest boxes.) 3) Will it hurt chicks that are soon to hatch if you have dusted the broody hens?
