Ive been breeding red tailed boas for years and never had this situation come up, the boa is 7 yrs old about 9 foot and very girthy was never bred until this season. all was well and her expected due date was april 15th, on wed the april 7th i found two dead babies in the cage fully developed, i did not disturb her until that evening when there were no more babies, the next afternoon i soaked her in warm water for about 2 hours and put her back in her cage with a huge black hide box, she looked to be contracting mouth wide open and the mass was reaching the vent so i once again kept the glass covered and left her the next morning still nothing , she is huge probably 40 or so babies still in her, i dont know if this is ok or should i have her over to the vet, any ideas of other expeiriences like this please let me know thanks again.
