This web-site is focused on breeding for the pet rat side of things but the information is still applicable to breeding feeders...just don't post comments or ask for help if they find out you're raising FOOD, lol!

I'm by no means an expert at raising them and get lost in a jungle of allele locus and what constitutes a self vs. an Irish Berkshire (Irish Carbomb!? Yes, please, and a double at that!) but what I've found to work for me: I run mine in 1:2 ratios of males to females. I have a couple concrete tub racks that mine live in. I've recently begun rotating the males out on a weekly basis, just to try and stagger the production some, as I had a few weeks with six or seven litters all at once and not enough snakes to feed them to. Food, water, and the correct temperatures (mine are in a climate controlled bonus room over my garage and the temps run in the mid 70's). I feed Native Earth (Harlan 4018) and occasionally grapes and/or organic plain yogurt and/or hard boiled eggs, especially when a female is nursing.
I've tried all the possibilites as far as leaving two females together, separating them out, leaving the male in with two girls, taking the male out, leaving the male with a single girl, etc. I've not really found anything to work better than another and couldn't really say except that it comes down to personal preference. I remove my males from the tubs just to give the females time to nurse and recover from their pregnancies so they aren't being bred back-to-back. It's slower but with only six snakes, it works for me as far as production and having the right size food item to offer when I need it. Here's an awesome chart that helps to give you some ideas as to how to cycle your males/females:

As one of the other posters suggested, don't stress it. I did when I first got started with mine and it didn't help anything. Put a female and a male together and they'll figure things out, lol! Good luck, sorry for the novel but I hope somewhere I offered some info that might help. Take care!
