i tried the davis spray idk if id works yet, as far as the damn nits i tried the coconut but them things are really stuborn, i plucked the feathers that had nits in them most were the baby feathers, the bird came from the farmers market ive i have gotten chickens from this "family farm" before and theyve always got pests. often they cramp the birds together they bring to market and someone is getting pecked bloody and i just cant unsee it and bring a bird home. so now im a silkie mama crossing fingers
