All my dogs are chicken broke. I've had chickens for about 4 years, and they all get along. I have about 20 chickens and my dogs don't bother them or chicks. Today I got guinea chicks and my youngest dog, who is a year old and was raised with the chickens, killed them all. He went berserk. I didn't see it, as it was over with when I went to check on them. The brooder was moved over a bit. Has anyone had this happen? I want to get some more, as I can secure the pen they were in until they grow, and bond with some of my chickens that I will keep penned with them.
