made the switch to rat pups !

Aggro slammed his first rat pup from coming off mouse hoppers he hit the 150g mark and the rat pup I fed off was 24g am I on the right track? Also the the pups that came in my order are a little on the large side being that I only have 3 that are around 22-25g and the rest are between 30-36g should I hold off to feed the larger ones or will he be good to go

I would say Aggro should be fine, although I would purposefully feed off the smaller ones first just to get rid of them and slowly offer the progressively larger prey. From what I've seen on other posts like this is that about 20% of your snakes weight is a sufficient prey item. But otherwise you're on the right track, wish you the best of luck, switching to rats will make you life easier.
