I have a Bantam Cochin that has been broody for 8 days. Yesterday I got back from vacation and candled her eggs (all of them are fertile), but I noticed several little black ants crawling in her nest, on the eggs, and on her back!. I am really concerned that they will hurt her and her chicks, when they hatch. Is there anyway to kill the ants without poisoning my hen and killing the growing embryos? I have lice powder stuff for chickens, dogs, and garden plants, but I have never used it.Thanks!
