Good questions and valid points. I breed ASFs to feed to 4 of our breeders who are stinkers. I have also started some babies on ASF hoppers too but they always switch to rats with no problem. I haven't sold any babies that weren't eating well on rats and I always include feed/shed/genetics records with the ones I've sold. Generally I start babies on hopper mice then switch to rats asap. If I ever sell the breeders that eat ASFs I will absolutely disclose that they are ASF eaters. I feel any and all responsible breeders will disclose that to possible buyers. While some people shy away from ASF eaters, I actually shy away from mouse eaters personally. As a breeder I don't want the hassle of feeding 2,500g female multiple mice and I don't want to breed mice either. The smell permeates our house even when we only have a few in the basement. So it all comes down to preference and availability.
