How do I train my dog not to chase my peafoul. The dog is a boarder collie cross and she has already maulded two of my call ducks. I don't thing she means to kill them but she chases and tries to play with them and they end up dead. She does the same thing with kittens, she steals them from the barn and takes them on the front lawn and plays with them but fortunately the kittens are tuffer than the birds.I would really like to let my peafoul free range but I dont want to take a chance till I figure out how to get the dog to leave them alone. Any suggestions would be appreciated.
