question about feeding

[Dunner]

hi, i had a question, if anyone can help me out that would be great. i have a 10 foot male burm, he's currently eating chickens or rats, mainly chickens though. and i was just wondering, i have access to pre killed weaner pigs, about 15-30 pounds, at what size and weight would he be able to eat these. oh also they're human grade, it's from a pork farm. thanks

I feed an 8+ft boa (50lbs) jumbo rabbits that are about 12lbs with no problem
