They look to be the correct morphs.
As far as feeding goes, have you tried feeding live to get the female going again? Another thing you can try, I have a friend who had a female go off feed for about seven months as well. She kept trying to offer her FT medium rats. I suggested she try FT weanlings. She took the weanling immediately. She fed her weanlings for a couple feedings, then bumped to smalls for a few feedings and now is about to get her back on mediums. When they haven't eaten for a while, I think large meals are just a bit overwhelming.
When adults are on feed they should eat weekly just like any other size animal. They may occasionally skip a meal but that's just BP's.
I think you want to get your female eating regularly before you start pairing her. If she isn't packing on weight it probably doesn't make sense to breed her and take a chance she won't have a successful clutch or worse yet, over tax her body.
