I have an ant problem in and around my coop. They come from pine trees and are menacing to say the least. I have 14 girls on the verge of laying. I found ants in the nest boxes a few days ago and sprinkled the shavings with Seven Dust to get rid of them. Tried DE first, but that didn't work. When they begin to lay, will the eggs be edible since they will come in contact with some of the Seven? Does anyone know a tried and true method of keeping ants away?
