Herding breeds tend to chase. Great Pyrs, Maremma can guard birds well. They'll need to be used to birds or acclimated to birds if they haven't worked w them before. A Pyr or LGD (livestock guardian dog) rescue group may be able to find an LGD experienced w birds or trainable to birds...with just 2 acres a retiree dog would be perfect.
