I have a pair of Boas that have been going at it for 3 weeks now. If say it took the first time they locked up three weeks ago, how long would it be before she dropped? How long are they gravid? Also, if it's her first clutch what are the chances of her being successful? I have never tried breeding boas before and would like to get as much info as I can. Also, is there a certain temp. I should keep her at? Thanks for any info you are willing to give!! Bobby
