If i powder the birds and the coop will it hurt the eggs that are hopefully hatching on the weekend and will it hurt newborn chicks? I also have call ducks in the same coop. Do i have to worry about them or is it all the same meds when it comes to powder. The only reason i saw the little bugs crawling on the eggs is because it was the first time i put my glasses on when i was in the coop. I feel so bad for not noticing them sooner.
