Hi, I'm new and this is my first post.
We have found that our Great Pyrenees is by the most reliable guard dog we have. But, I guess one should not expect much guarding from two Labs and a Brittany puppy. After the Pyr, Fluffy, was old enough and socialized with the chickens, we have not experienced a predator loss for the year she has been on guard duty. Once matured, the Pyrs focus is to guard. I think by just sitting on a high vantage point and barking with the booming bark lets the predators know that her territory is off limits.
Our training method for Fluffy varied a little from the typical LGD training. The chickens are much more delicate than sheep the LGDs typically guard. Plus, for our little farm there is little need for Fluffy to bond incredibly close to the birds. The birds and dogs roam free on a 1 acre fenced area. Hence, all we needed was for Fluffy to not eat the chickens. Since, the birds are in the yard which is Fluffys territory; she will defend them and the yard.
We have had Chinese geese which did a good job alerting the dogs to just about anything abnormal that occurred around the yard. But, the geese were not very useful if the does were not out. For one, the chickens didnt care for the geese, hence were not near them. Second, the Chinese geese are down right violent. When penned up they killed a young duck and a chicken that made the mistake of getting into the geese pen. The geese are no longer with us.
Interestingly, when last winters snow obscured the fences, we couldnt leave Fluffy out with the birds (Pyr have a sort of wanderlust). We hadnt seen a predator for quite some time, so we thought it was safe to let the birds range free (our chicken run was buried). We were wrong. A bobcat ran through our flock with a ferocity we had not experienced with the red foxes. The geese were no help. We dug out the fences and Fluffy was back on duty. One morning, when we were all out in the yard, dogs (4), me (digging out fences) and all the birds, the geese made a heck of a lot of noise. The bobcat had slipped into the yard (I was distracting the dogs by my activity). Before I could get to the birds, Fluffy had the bobcat treed. One goose suffered a superficial wound.
I think the Pyr made the most sense for us and our climate. Other guard dog breeds might work out well, too. They would require good socialization with the chickens, which I have some thoughts on. If anyone is interest in how we socialize the dogs, let me know. I wrote up a little procedure.
