They've always been mousers and I don't want to starve them out because I just got them and are underweight. I'm going to mouse them all the way to breeding weight and then after breeding their going to switch.
I see what you're saying. In that case, I definitely would only give them one of those mice, if they are underfed, so you don't overload them. If you want, you can feed on a 4-5 day schedule, so they get more calories but not quite as big a meal in one sitting as 100g in mice.
Add: On the other hand, a starving BP could be more likely to accept a rat than a well-fed one. Just a thought, but your plan works, too.
