I bred Kenyans back in the 90's. I typically had 1 male to 2-3 females. I kept them on sand with a basking light at about 100 degrees. All I would do is leave them together and let them do their thing. I feed them in separate feed containers to eliminate ingesting the sand. I got quite a few litters form them. Its a bit tricky to get the young to feed on pinky mice, but you have to be persistent and they will eventually feed. Good luck.
