I use a rat rack with five tubs four females per tub and i use two males to rotate around the tubs. I keep the males in with the girls for two weeks. When i see a female prego i move her to a 116qt sterilite tub.

After she gives birth and all are weaned she goes to the bottom of the rack for a two week break. I keep the weaned ones in the 116qt and use a new 116qt tub for the next prego.

I hold back two or three of the weaned females and feed the rest off. I give my retired breeders to my brother who feeds them to his boas. I try and bring in new male boold after about nine months. Thats what works for me.
