Iv been looking over tub setups for breeding your own feeders. I will eventually move to building a rack if breeding proves worth it.

My question what kind of tubs do you use with a lid since its not going to be in a rack?

All the ones i see at like wal-mart are like this.



All the ones i can find have the raised up edge, now iv read this will allow chewing as the rats would have an edge to chew on. So what could i buy that has like an all flat surface that the rats could not chew on that is a tub. Iv seen the mortar tubs but them seem like their only good for racks.
