My maremma did the same thing to one of our chickens when we first got her. She was young and playful. But they are dogs and all dogs still have hunting instincts. When the birds run from the dog, the dogs instinctively start chasing them, and it escalates very quickly after that. My dog eventually learned that she does not chase the birds, and that the birds are off limits. But they don’t automatically start out that way. Maremma as I have learned are not the brightest breed of dog. I used to have a border collie and we got her when she was a puppy and she always knew from the beginning once we got her adjusted to the birds that she protects not hurts them. My maremma however after we’ve had her for 5 years now still needs reminders every once and a while. It’s just the breed I guess.We purchased two Livestock Guardian Dogs a month ago and just recently we are losing hens one by one. But this morning we found a dead hen which they had caught and mauled it. It's organs were exposed. We thought LGDs instinctively are protective. They have been out with the 50 hens for 4 weeks. The dogs are Maremmas.
Can anyone give advice?
