Just want opinion but knowing what I know now and if I had a Sakata and if I planned on staying in that house permanently, or at least for many years, I would build the adult sized enclosure now. Figure out how big you want it and start building it now that way you do not have to keep adding on and adding on and adding on like I have done. You can at least figure out your parameters and build a barrier, I'm sure you will have to reinforce it later if you were worried that it will be so big that you would lose the tortoise at the size you can always divided in half for now with a temporary barrier. But I would take that to the Sulcata section and let the experts in that species tell you more. Housing large powerful tortoises that can be destructive is definitely a specialty. Maybe see if you can see some people's outdoor enclosures in person to give you an idea, you have a little bit of time before he gets huge
At what she'll length should i move my sulcata to a bigger outdoor home he/she is 7or 8 inches long.
Tom, I couldnt help but to think about chickens the way you discribed it. lol similar routines.As long as yours continues growing and is 8-10" or more next spring, that is when I'd make the move outside. Try to put the tortoise outside all day long in the new enclosure, weather permitting of course, all through early spring. Put the tortoise in its heated night box and let it learn to walk out on its own. Have the enclosure all built, with night box installed and thermostat set. Keep up this routine for a good month or so. In late spring or early summer, when the weather is good, just start putting the tortoise on the ramp leading into its night box at dusk. Help the tortoise to learn to walk in on its own. Keep this up until you start going out at dusk and finding the tortoise already in its box. Lock the tortoise in every night and open the door every morning.
