Rat Rack tubs

I got some concrete tubs from lowes that measure 26" long x 20" wide and 6" deep. Are these tubs good for a birthing rack for one pregnant female or for keeping weanlings in? Thanks for your time.

Those size tubs are good for breeders. I keep one male and 3-4 small females, or 2-3 large females, the girls get pulled after 3 weeks into the large size Van Ness litter pan rack to birth and nurse by themselves.

I also keep weanlings and grow ups in that size.
