I have a Great Pyrenees/Anatolian mix we rescued at age 1. We moved to land when she was 4ish. She chased the sheep that were staying here temporarily. I now have chickens (born in July). She loves to chase fast moving and fuzzy critters, so I cannot trust her around my chickens. However I have read you can train them as a pup to be around these animals. They are stubborn and hard to train, but I’m guessing it’s possible with lots of patience and discipline….That’s not me. That said, she is extremely affection, loves people, playful, and loves to play with other dogs, but is choosy about which ones she accepts, especially in her own territory. Other characteristics - stubborn so hard to train, but overall well-behaved anyway. Super chill, but can be mischevious. goofy. Her protective instincts which would be helpful if I were not worried about her using the chicks as a toy are: barks a lot, wold definitely chase predators away. She chases large flying birds (hawks, eagles, geese….), and even small birds, chases squirrels, rabbits, you name it. She loves to be outside at night and just lay there and watch her land… but also bark, so if not great if you have nearby neighbors. they definitely love to roam, but when our’s does escape, she never goes far and always comes back home (thankfully safely so far!!). She is beautiful. SO… I think if you get a pup and can work with her diligently, you will have luck!
