At what size would birds of prey stop being a threat to tortoises? I have hawks in my area and wonder if they would bother a tortoise free roaming in the yard. When I had my little guy, and for my box turtle, they always stay in an enclosure with a wire lid and only free roam the yard with direct supervision. I imagine a larger Sulcata would need less babysitting. I also imagine I am not the only one with hawks in their neighborhood.
