How long to keep males/females together?

[Stewart_Reptiles]

My question was more expressing concern over the state they were originally kept in (the feeder breeders) and where I should go from that point, as opposed to bringing home breeders that I knew for sure weren't pregnant.

Does not matter same thing, separate them in group of 1.1 or 1.2 or 1.3 (no more than one male with a group of females) and remove the male when visibly pregnant.

When you remove the male rotate them with another group of females do not house the males together. Once they are sexually mature and have been exposed to females even males that were raised together and were doing fine will now become aggressive and fight.
