I want to get my rodents out of tanks and into tubs in a rack.

What size tubs would work well for 1:3 or 1:4 breeding colonies?
What size for grow out?

I will build them with wood frame and mesh tops with the food sitting on the mesh. I guess I am wondering most about the height of the tubs so the adults and juvies can reach the food.

I have found tubs that are 4,5,6 and 7" in height. Can they reach the food at 7"? Is 1/2" mesh the right size for the tops?

What do you guy/girls use for tubs?

Thanks
