there are some cases that they do, and since you plan on breeding and selling off some of your hatchlings they customers may be quite hesitate to buy from you since asf rats are hard to come by, and would be very hard for them to acquire to feed their bp they got from you.
I agree. Personally, I would not buy from a breeder that has been feeding the hatchling ASFs. I would worry that once I receive the hatchling it would not take domestic rats.
