Is the female truly eggy or is she just big from eating more than her share in the sorority? Conditioning is usually recommended both the male and female in their own small tanks side by side - place something between the two tanks to block their view of one another - don't let them see any other betta at all.
Once a day for 5-10 minutes allow the pair to see one another after a meal..
Feed 2-3 times a day live and frozen being ideal with some pellets tossed in here and there is fine.
I would make sure this female is eggy before attempting - once she is in her own tank then don't feed her for 24hrs and see.. if her stomach is still very enlarged then she is most likely eggy, if not then she is just large from being a piggy with the other girls.
As for fry food...
BBS is fine after a few days.. frozen food most likely won't work yet. You won't be able to chop it up small enough and most fry will refuse anything that isn't moving for the first month or so.
Best first fry food is Banana worms, walter worms, vinegar eels, infusoria.. they are micro cultures and very very tiny.. and BBS after a few days to a week as some of the fry will be too small to eat the BBS. Most times when BBS is fed it's after the fry have spent a few days eating other first foods and grown a little bit to be able to eat the BBS without choking.
I would look into ordering either Banana or Walter worms from a breeder and getting those cultures going before you attempt to breed, it can take a few days for them to ship and then another few days for them to set up.
Food is very important to fry - for overall health, future health, growth, etc..
