Ok, So I have a question for readers of this thread/forum

I have to temporarily house two of my snakes together while I order heat tape and build an enclosure for them as well as other snakes coming in. I have a full grown 5' and over 1500 gram male, a 2.5' young male, and a 2' young female. The female i'm estimating is about 500 grams. I am going to house the two in a 100 gallon tank with 4 hides- two on each side of the temperature gradient. They have all been near each other, and quarantined adequately.
I'm worried that if I stick my female and the young male in the cage together, that they would attempt to breed- and possibly jeopardize the female's life if she becomes egg-bound. I'm not even sure if she's capable of breeding yet- nor the male for that reason. I dont want to stick the big one in with the others, because i'm worried about size problems.
It's only temporary, a few weeks at most.

What should I do?
thanks
