I've been breeding asf's but I've been using tanks which I HATE
I wanted to make a rack with mortar tubs and use 1/4 inch hardware cloth.
The tubs are 27.5x19.75x6

I was thinking of a colony of 2.10 in each tub

I have a few questions:
1) Anyone who use these have issues with chew outs?
2) Can they eat lab block through the 1/4 inch screen?
3) How do you get the tubs out during cleaning time with the valves through the hardware cloth or do they come out easily (since you'll have to cut the cloth to fit the valves)

4) Weaning. I want to set up holding bins also in tubs if not 40-75 gallon tanks (i have extras). I was going to do one for males one for females and my question on that is, if you have one breeding groups babies and put them in their holding bins, can you take another breeding groups babies and add them later on? How long can you keep adding new rats because I hear that they get very very territorial once they're in a colony.

Photos of your setups?? I'm looking to produce 500-1000 of these guys a month!
