Well, I would think you could train it since it is still a pup. W/only 3 acres, I assume you are rural and that the 3 acres have some kind of fencing and fence posts.
Pyrs and most lgd breeds suffer from Wanderlust! You really need to back up that livestock fencing, if that's what you have, with several rows of electric-charged fencing to keep the bugger at home and keep him from being a nuisance to your neighbors. Fence it like you were trying teseo keep in goats and w/a good charger. Then maintain the charge.
Our part of Texas is full of pyrs and pyr-anatolian crosses. They often wind up in our horse pasture from Heaven only knows where. They always come up for a pet on the head and are calm around the horses, and then sooner or later wander on to whereever they're going or wherever they've come from. I probably won't have such a happy attitude about that though, once my chickens are in place! These are all cattle and goat dogs, not poultry dogs.
If you train them right, though, they sure can be an asset to keeping your chickens safe. But, depending on the dog, that can take as long as 1 1/2 to two years before the dog can be trusted w/something as delicate as chickens.
My farrier had a pyr for a pet and absolutely loved it, but because it was a pet and not properly trained, that one was a chicken killer.
