I have just gotten my first chickens and they are all only a few days old, I also have an australian shepard mix , a red tick hound, and now a rat terrier. The hound is sometimes howling at my pen, but I sprayed her nose with vinegar and she stopped. The rat terrier watches them when she thinks we are not looking , but my shepard just won't stop barking and stalking them through the cage. I woke up this morning and she had tried to dig in ( unsuccesfully) but I need to train them to protect the chicks , not eat them. Can anyone tell me how to do that , my neighbor says to beat the dog with the chicken that it kills, but I don't want to let one die before I can train the dog. I would also like to have the adults free range , so I need to teach them before the chicks are grown, I have the chicks in a fully enclosed little run for protection at the moment. Any suggestions would be appreciated.
