I have a GSD who is a vicious hunter of chicken poo. She even will follow the poor birds around trying to lick their butts. I've yelled and yelled at her. It only makes her stop until I turn around. Spray bottle of water and e-collar haven't worked to stop her either. It's the nasty habit I haven't been able to break. She's good with the chickens, they can climb all over her. Just she gets all excited when one poos. My aussie/heeler doesn't touch the stuff. Does anyone have any ideas on how to stop this nasty habit of hers?
