On the whole free-ranging deal:
I have found that if the typical Oriental stag is not free-ranged at least until near maturity then there are nothing but health issues facing you. That is why I prefer late maturing strains of Asil.
I don't free range the pullet because they mature much earlier and will kill the stags.
Typically, I turn every stag out at 12 weeks of age. It is ROOT, DIG OR DIE from that point until the begin fighting too bad (around 10-14 months).
I do lose some but not many. Great thing is if the heavy breeds such as the Kulangs and Shamo start roosting in trees early that they are continue it through out their lives. Mine will roost in trees 20 to 25 feet from the ground.
