Just a thought. If you have a steady supply of ASF, that's great, but BP's can imprint on certain prey items. In other words, a BP can learn to love ASF's, but if you try regular rats down the road, may not be as likely to take.
I've heard many cases were it's been tough to switch a BP back to regular/normal rats if the ASF supply dries out.
Not trying to be a downer, but know what you are potentially getting into.
Also, if someone has more experience here, please chime in. I am just going by what I've read over the years and I've seen online suppliers of frozen ASF's stop selling them.
If you are talking live, I imagine the same thing applies, but don't have direct knowledge or experience of live ASF breeders.
