While I don't breed my boas (haven't decided to yet at least and won't be able to for a few years even if I do) I do breed my pythons and I had a similar season with them. I'm sorry to hear you had such poor outcomes, but then again, at least the viable neonate proves that she can produce healthy young.
Tell your daughter Happy Birthday from us! If she is into boas also she should at least get a kick out of sharing a birthday with the new addition!
