I made a pen in my base to breed Lox. Small cage, can only hold 4 at a time. But, I take two outside the base as they reach maturity each time.

I have probably around 50 or so roaming outside the base. This protects the base, nets me tons of neck,boar and deer meat, hides, dark metal, gold, etc, etc.

It's a never ending revolving door of goods.
