OK, quick question: I'm looking into getting racks for breeding mice, rats, and ASF for feeders with my own collection as well as selling to the pet store I work at (we're trying to step away from breeding mills as much as possible as I mentioned in a previous thread, including breeding hamsters...but those aren't gonna be bred in racks). I'm wanting to buy racks for the feeders, but I'm confused on tub sizes.
What are the appropriate sizes for them? And what's the appropriate colony size; like, how many total breeders per tub?
