Mine looked just pitiful when she was off her eggs the first year because after she refused the first meal, I didn't offer food again until after the eggs hatched. I now know that one refusal doesn't mean that they'll skip meals throughout the process but they can be more fickle about what they will eat. My females' regular meals consist of small or medium rats and they never showed interest in those while brooding. I've had good luck offering live and fresh killed rat pups, though.
