Go for it. Assuming you're picking him very young by the time he's ready to branch he'll be so tame and dependent on you that he won't go too far too soon. Put a bell and transmitter on him and you'll be all set. I was just telling my wife yesterday that the next gos I get will be a tiercel that will stay out at hack for a long time. My female was out for 27 days and was just really starting to benefit from it, then she killed a neighbors chicken and I had to put an end to the hack. My female learned how to fly and land and kill while out, she came in every evening and was tethered to a pole perch in the house. We went right into "hunting" from the hack, more like outings with lots of chasing and very little catching.
