I'd say the chances are pretty good. I haven't bred BP's yet (plan on it soon) but I've done ALOT of research and from what I've gathered, Females should be atleast 1500 grams, some have bred and produced at 1200-1300 before with no problems.
So, if I were you..I'd be pretty darn Happy...and like the others have said, Get the bator ready!!!!
Also, BP's can be bred anytime of the year. A little artificial season changes will do the trick...
Good luck with everything.
