We see you are located in NY state. If you're near the Catskills shoot me a PM.
Live rodents are prohibited from New York state shows. The shows in Hamburg, PA, are the closest shows to the NYC metro area where live rodents are permitted. We were there 3 weeks ago, so much more diversity than the White Plains and Poughkeepsie shows, nice change of pace.
"Feeding several to the burm..." are you talking about that monster in your photos? She might need several colonies for a feeding, not several ASF's. Also, burms are a Southeast Asian (and Florida Everglades) reptile. ASF's are an African rodent. Go with prey items that her great ancestors were eating when her DNA was still in Burma.
One of the reasons why ASF's usually work for picky BP's, and work better for BP's in general, is 'cause they've been eating them since dinosaurs were pooping in puddles. Rattus norvegicus is not a natural food item for BP's, despite the fact that hundreds of thousands of captive BP's grow fat, literally, on them.
Yes you are right re their aggression, but as long as sexually mature adults are not pulled from their colonies and mixed with sexually mature adults from other colonies there will never be any trouble.
