I have a 30+ week old Light Brahma who has laid a total of 3 eggs, none of which had appreciable shell. We have no egg eaters and she has no sign whatsoever of being eggbound. I have increased A, D and E intake, offered electrolyte, free choice oyster shell, extra protein, and...nothing. She is not being pecked or hurt by the birds that she is in with, is friendly, sweet, and even tempered. She's just not laying. I'd prefer to not put her on the menu, and will give her until Spring to figure it out. Is there anything I missed?
