One of my 3 hens has lice. I think I am going to treat her with permethrin. I've read that I should also spray inside the coop. Spray the walls and ceiling. I'm wondering if this is necessary, considering the temperature is below freezing where I live. Wouldn't any lice/eggs end up freezing to death if they came off the hen and were loose inside the coop?
