I know I post a lot on here, I'm just new & want to learn absolutely everything I can.. I have 2 1 year old (approx) Female Jackson chams, & would like to know about free ranging? What is it? When can I free range? What's best about free ranging, can I have both girls out at the same time? Can they 'hangout' at my work desk, etc? I'm Learning a lot here, & just want to know as much as I can.. thanks!
