I'd say they're still building follicles at this point. Bowl wrapping is very common in this stage, and it is extremely rare for females to feed when gravid. Though that could have been their pre-ovulation shed. I'd say just keep pairing for now. I had the same thing happen a few years back - my "gravid" females were eating, and ended up reabsorbing their follicles since they hadn't ovulated yet and I had quit pairing them for like a 1-2 months or so.

Best of luck with them!
