Hi guys! I have one 8 month old sucata (2 3/4 in) and one 5 month old california desert tort (2 1/2 in). I just built a 4x8 wooden outside enclosure for them (i'll post pics when everythig is set up). It has a chicken wire top so animals cant get to them. Once my torts get bigger, i'm planning to let them roam our backyard freely. I was just wanted to hear your thoughts on how big they need to be to not be picked up/eaten/killed by predators like crows and hawks while they roam the backyard. Thanks!
