I thought all along that my BSL Daisy was laying because the eggs were small and several times she came in the coop when I would gather the one egg. Tonight, there was only one egg, but a BIG one and my RIR Lucy came inside. My Lucy has been squatting for weeks, Daisy not so much, but she is the one I see coming in and out of the coop. No I wonder if it was Lucy all along and she just gave me a whopper today. LOL!! I do think there is a color difference.
