Folks, the yellow is stored in the female's legs and she gives it up during her laying cycle. It's entirely natural. It's where the yellow of the yolk color comes from. She also stores up calcium in her long bones for the shell making. Again, entirely natural to them.
I don't pay any attention to trying to keep a heavy laying female's leg yellow. If her legs are washed out? Likely she's a good layer. If a bird that supposed to be laying heaving for you has pristine feather and yellow legs, she's very likely dogging it in the laying box. Pick her her up and check her pelvic bones and vent. Chances are good she's a lousy layer.
I had a stunning, I do mean stunning female in the breed pen last year and she never did turn ragged feather nor legs turn light. Never did get eggs from her either. She got eaten.
