Husbandry's good, looks like. Humidity could be a teeny bit higher. Cage aggression is a myth. Most snakes will stop feeding if they're in a different enclosure to eat. And think of it this way, won't they start to associate you going in there to pick them up with feeding time?

Besides, a bite from a baby BP feels like absolutely nothing and unless you go in there with your hand smelling like prey the likelihood of getting bit is low enough it's laughable. Baby BPs are mostly bluffing when they 'S' up/hiss/strike. Sometimes they'll strike and make contact but never open their mouth to bite.
