My Brahma Lady Di began laying again after not laying for over a year. The eggs are all like the ones pictured here. They're tiny, lack any yolk, and are rough in texture as well as much darker than her original eggs. Can anyone tell me what this signifies? Is she okay? Is she simply nearing retirement? Will she eventually start laying normal eggs after these tiny practice eggs? She appears healthy in every other respect. The eggs average an inch in diameter.
