I don't have a colony going yet, but I will in the next year. I have been doing a lot of checking around to see how people have theirs set up and I am hung up on one big difference.

Some rat breeders use larger bins, put 1.4 or 1.5 etc...rats in each bin, let them breed, take out the male, and just leave the moms all together to raise their litter.

Other rat breeders move pregnant rats to their own individual bins to raise their litter (ala, Ralph Davis' youtube video).

I am thinking the first way would be easiest in terms of maintenance, but can others chime in on what they do and why? Thank you!
