If it left a bump I’d say that’s plenty big enough for now. You don’t generally want to feed anything larger than the snakes widest girth with BC. And once they’re fully grown they don’t even need anything as big around as they are, maybe like 3/4 their girth.
Stick with the small rats for a bit and see how she does. You’ll honestly have a hard time underfeeding a boa but it’s seemingly pretty easy to overfeed them.
My Pokigron Suri is about 250grams, 2.5’ or so and just shy of 1.5yrs and will be graduating to large mice for the time next week. He only eats every 10days currently but I’ll probably push him out to 12-14 days as prey size increases.
I portioned out my last feeder order of 50 large mice by size so I can incrementally increase prey size for both my Suriname and my Argentine Boa. The large mice ranged in weight from 18-30grams in the bag I got from cold blooded cafe. Once they’re through those mice they’ve got weaned rats waiting in the freezer.
