Elizabeth, I can see after re-reading my post this morning that I was not totally clear about the Cinny females -- my bad.
The Cinny girls that laid the one egg clutches were DIFFERENT 1600/1900 gram virgin girls.
As far as giving girls a year off between clutches. From talking with experienced breeders and considering it logically -- I am less likely to be concerned about a female that laid 2 eggs or 6-7 slugs than I would a girl who dropped 10 fertile eggs. It takes MANY RATS for a 2500 gram girl who lays 8-10 eggs to put weight back on for the next year!!!
Slugs/1-2 egg clutches use much less body weight and girls are able to get back their body weight quicker for the following season than do females that lay big clutches. They do need to eat enough over a few months to restore nutrients for the next season.
