We have had them in racks for about a year, the only problem we had is we had to change our wire from 1/2" to 1/4". We have had nooooo chew throughs. If one did excape the cat loves to hunt them as they are more of a hunt than mice. ASF have almost no SMELL!! The minute we bring mice back in we can smell them.

We run 1 male to every 4-6 females per tub. If we put more than one male in we have big problems!!!!!!!

The males will fight and chew each other the whole time.

We also learned to remove babies when at the hopper stage, as again the male issue comes up. Needless to say males disappear first out of every batch.
