Please think carefully before deciding to breed. There's a lot to consider and a lot to learn before just throwing two breeding sized snakes together. Actually there's not but to do it responsibly there is. There's quite a bit of good info on here if you use the search button. But most people that I know recommend 3 winters or 1500 grams for your females. And one winter and 700 grams for the boys. I've heard of buys breeding as small as 350 grams before there first winter but I don't recommend it. Also some people will say 1200 grams for a female is ok but I've only bred girls that small if they are on their 4th winter and just won't grow or eat well. And they always produce smaller clutches for me.
