Not sure if this is the place for this question, but thought it might be. Is there any breed of dog that is particularly notable for guarding poultry, especially free range birds? We are probably overly cautious, but we have a large population of coyote, coons, etc. and want a dog who would chase off and defend the flock? As there are certain breeds of dogs who are particularly good with herding, etc., are there any that would excel with regards to chickens? Mind you, we do keep our birds in at night but are wondering if anyone might have some insight into this. Thanks, in advance.
