My dog went through some hard core training (which wasn't that hard at all, since I love spending time in the chicken yard). She spent a year being totally fine with the chickens, resting with them, coming with me to visit them, AND not eating their poop when I tell her. But after a hormonal broody attacked her, she has been slightly scared of them. Sometimes a few chicks would chase her as well. I feel pretty bad, so I dont take her with me as often, but she loves to follow me as well. She still is okay with chickens, but definitely is a little more cautious. She is pretty small though. We do have another dog who would go for chickens any day.
