Hi there, This is my old English game bantam, Marilyn. She's eight and a half months, and she laid her first eggs back in December. She laid two eggs that first week, and since then I haven't seen a single egg from her. She's always with the other chickens and she's never disappeared, so I can't imagine that she might be hiding a clutch somewhere in an attempt to brood them. She's perfectly healthy and her crop feels normal. Is this just because she's a bantam, or should I be concerned?
