I am into my third year with BP's. I started with one normal, and now have over 60 animals, and currently have 7 clutches in the "cooker". I do a lot of things to keep my animals interested in eating, including breeding ASF's for those picky ones. Sometimes I wish I never would have tried to cater to the finicky ones, because now I have to.
They will eat when it is time. Maybe some others have seen a BP starve itself, but I have not. The exception of course is newborns, but yours are well started and will feed. This also is an off time of year for some of mine.
They will eat at their pace, offer once a week, and if they don't want it, don't fret. Of course keep tabs on their weight. If they are sick that is a whole different story, but you didn't mention anything about weasing or respiratory issues.
