1. i would get one that i like but remember hes gonna produce babies you like also that you may not want to feed off.
2. i used to separate females untill my last breeding because they helped each other so much that i wont separate females any more.
3. yes you can separate him and i would because i have a problem with the males eating the young.
also make sure you have a good rodent food source, and i would start to get some more caging because before you know it you will have matureing males fighting over females and such, check out the diy section and pick a way to best suite you for caging to separate the young by sex. and then also think about how you are going to euthanize your rats when they are of size you need. oh and there is also the bedding thing, breeding rats will take lots of bedding so find something good and cheap no cedar or pine. hope this helps a little. and remember that everyone has their own way of doing things and you need to find the way that works best for you. also look into rodent racks, they are amazing! oh and do the math first on breeding vs. buying f/t in bulk. good luck and happy herping![]()
