Question on Breeding Large amounts of rats

[reptilegirl07]

I'm looking to produce 3000-5000 rats per month

How many 7 tub high racks would I need to make this work (including racks set aside for moms giving birth)

I put 1.6 in each tub for breeding and 3 for birthing and am using the cement mixing tubs

And with a 1.6 in each tub, is it better to separate moms when preggo or not? I hear a lot of debate on both sides

Thanks!!
