She's as smart as a whip. She knows FINE well the chickens are no, but she does it anyway.
I taught her to ring a bell in five minutes when she was a pup... Pulled it out again 6 months later, and she remembered. I can drop meat on the floor, tell her leave it, and she will. She's pretty good at heeling, getting back into heel, sitting, down, catching food, etc... Chickens are her one vice. She'll be good if she's on a leash or if she's behind a fence with a shock collar on.... But if she gets out she will slaughter birds.
