Breeding a ball python female too small?

okay my friend just gave me a bp 4 days ago male. i put him in with my other male so when i put them with female they will want to breed more. well i went on a lil road trip well 1st my "male" is 800 grams the male i put him with is 700 grams. well i got home to day to c them breeding. so i pulled them apart i no im not supposed to do that but i did. them snake i thought was a male. is it possible she will ovulate. if so im sure she will die kuz shes too small. another question is it possible to get her weight up in the next 5 months by 400 grams so shell b big enough to lay them eggs. thanks so i did finally probe the new snake and it was female. i was talikng this guy and he say he had a female at 800 grams breed just once on accident and she produced one fertil egg.
