Well, we are in our first 6 months of raising our chickens - living in a somewhat rural area. We have seen bobcats, hawks, owls, coyotes and about two months ago a couple chickens were taken! We believe it was a hawk but could have been the bobcat. We started and had always thought we would eventually get a Great Pyrenees but this kind of moved that up in the schedule. We got him about 8 weeks ago when he was 4-5 weeks old. He has been great with the chickens till about a week or so ago. He is just getting more playful and started being more engaged with the chickens - starting to chase them. He is about 12 weeks now. Every night the chickens go on in the coop on their own and right before we go to sleep we put him in with the chickens in the coop, which is a shed that is about 8x8x9' tall. On Saturday i looked outside and he was chomped down on one of our hens, i walked outside and said no and he stopped and cmae running. Today my wife got home and he was eating that same hen. She is unfortunately dead. I spend as much time as i can with him making sure he knows the chickens are off limits. Does anyone have any answers? I realize this is not the first time this has been posted but was wondering if since he has already eaten one - does that mean there is no way i could ever get him trained...??????? Thanks for any input.
