Beautiful PRB!!!!
I don't think rabbit pinks would be bad for your PRB but may not be best either. Problems with raising rabbits is I don't think the breed that often and you'd have to closely watch the litter to pull them all at the right size and have to freeze most anyways. And the PRB might have messy stools - no straw in the brick. I also remember reading somewhere you have to introduce and remove the male in a short span, ie they don't do well kept together.
I breed mice for hoppers to feed my babies and breed rats of all sizes for everything else. Rats are pretty easy to breed and can be kept together.
Mice - I keep them in colonies to maximize production, I always need hoppers - lots every week. If I'm over one week I can freeze for later or let them go another week to get a bit larger.
Rats - I introduce and separate females to give birth to more closely control the production rate. Introduce 13 females this week and 3 1.2 weeks later you have 13 litters of babies. Actually more like 11.
