I have my asf's in a rat rack with 1/2" hardware cloth.. I know the babies can escape but the room they are in is escape proof so If any do get out they will not get far and I have some humane traps as well. Well the other day I noticed 4 were missing from the grow-out bin and i checked the bin with mom/dad and they were in there!! They escaped and found momma.

Now I have to get some 1/4" hardware cloth I can't have these guys running loose..
