It all depends on how long you want them to grow before getting fed off.

If you put boy and girl babies together... and they are together long enough for someone to get pregnant... at that point you won't be able to add any new babies into that same grow out tub without fighting. Normally as soon as a pregnancy occurs, newcomers are no longer accepted.


I put the boys in one giant grow out tub, and the girls in another giant grow out tub. This allows me to constantly add new weiners to the tubs without any fighting. Each week I take out older ones that have been in the grow out tub a couple months and use them for my feeders. I can also at any time pull older guys and girls for new breeding groups.

Make sense?
