Tommorow I'm going to Wal-mart to buy tubs for my rats that I'm going to breed. Heres what I plan to do:

I'm going to go to wal-mart and buy 5 Sterilite 68L (10g) tubs. 2 tubs are going to be for breeding and a male and 1 female will be in each tub. These will be "The Breeding Tubs". Then 1 tub is going to be "The Holding Tub" and will house the 2 females are are waiting to mate. When the 2 females inside "The Breeding Tubs" are knocked up (exuse me) they will go into the birthing tub, and the 2 females that were in the holding tub go into the breeding tubs to get prego.

Once the females in the birthing tub have given birth, I will humanley euthinize each litter for my little cal king and corn. By this time the other females will be prego and will go into the birthing tub. Then the 2 females who have already given birth will go back into the breeding tubs to get prego again...and the process goes on.

Now, my real question is, what do I do when I DON'T need any more rats at the time? Do I house all 4 females in a tub and the 2 males in a tub and just wait until I need more or what?

I would really like some input on this...thanks.
