Crossing fingers for the rest of them. Yes, they do lose weight, however, one of my broodies barely lost an ounce. We took her off the nest twice a day. My DH heated a towel in the microwave and covered the eggs when she was off the nest, mostly so others wouldn't get in there. She ate what we brought her, drank alot, pooped a softball, then she would go back to my DH, stand in front of him and ask to be put back with her eggs. She'd tug on his pants leg, LOL! Olivia was a hoot! We left her in the regular coop till they were due to hatch, then put her and the eggs in the broody pen. She went into her molt immediately after they hatched and came out of it with flying colors, probably from eating chick starter for a month. She was in fantastic condition afterward.
