I tried moving my BPs to a new enclosure to avoid cage aggression and just found it too much work (I have very limited space). So I stopped and have been bitten maybe twice in the last 3 months because of it. Hardly a high price to pay. I don't bother with hook training either, I just try not to smell like an ASF or a rat. I just don't think theres a reason to feed in a separate container with balls.
Now if I had something like a retic you better believe I would be hook training that bad boy. But with a BP a bite is nothing.
