My chickens are free range and have been getting along great with my 6 month old Bernese Mountain Dog up until recently. The chickens have started coming down to the house and eating my dogs food. I understand that the food is not bad for the chickens and can actually benefit them from the protein in the dog food, but this is making my dog upset with the chickens. He's actually killed one chicken since they've been coming and eating his food. I don't know what to do now. Any suggestions or ideas would be much appreciated! Please help! Thank you! I'd also like to know if y'all have any tricks on how to keep my dog from killing any more chickens. He's not an aggressive dog at all and he doesn't go out of his way to get the chickens but if they come down to his food area he gets upset and that's when he chases them.
