I'd be carefull feeding them to your dog(s) if your dog(s) is a herding breed. It's possible that it could hurt them. Some herding dogs that are decended from the collie have a genetic mutation that makes Ivermectin toxic to them. You can find out for sure by having them tested--WSU does it, you can request a test kit from them online, I think it costs around $70. My son's Aussie had mange when he was a puppy (mild and he outgrew it) the standard treatment is Ivomec, but we couldn't use it because of the possibility that he carries the lethal gene. I don't know how much would be found in the eggs of a treated hen, but the vet told us if he was positive for the mutation even a small amount could harm or kill him.
ETA: I'd feed them to my lab mix and the cats, just wouldn't want to risk it on the Aussie.
