First off, yes, your male has likely not eaten because he is stressing from being in a new home. Boas are generally garbage disposals so give him some privacy, leave him alone (no handling), and wait another week before you try feeding him again.
Secondly, you should NEVER house them together. For breeding, you would pair them for a few days at a time so they have the opportunity to lock, then separate them. But as far as housing, they should have their own separate permanent enclosures.
Third, unless the male is het for anery or the female is het albino, by pairing these two, you won't get anything other than a litter full of hypos dh albino anery. Those are pretty common and might be hard to sell.
Boas can have up to 30-40 babies in one litter!! Are you prepared to keep that many babies for as long as it takes to sell them??
If these are your first snakes, I STRONGLY suggest you do a LOT more research and talk to as many long-term breeders as you can. Go to shows/expos and meet people in the hobby and find someone you can trust to mentor you. BE PATIENT and don't rush into breeding. Boas can have a higher risk for complications related to the pregnancy because of the nature of having live births. It is not something to be entered into lightly.
And I caution you - the boa community is very welcoming, BUT it is a close-knit community. If you go about breeding the wrong way, do it randomly or irresponsibly, no one will buy the babies. Just giving you fair warning up front. Our concerns are for the safety and well-being of the snakes. We also do like to mentor new people - but do it the right way and ask for help and be patient about it.
** They are very nice - I like the female ghost in particular. She is awesome.![]()
