We recently got 10 chicks! They are now 3 weeks old. I know mites can get pretty bad in zone 7. How do I prepare for this and prevent mites and lice from the get go? Do I need to put drops on them and 7 dust the ground? I have no clue. What age do I need to start medicating and deworming? We have small children, so I don’t want too crazy poisonous chemicals around, but I want what works best. Thanks, any advice is appreciated.
