My Buff Brahma started laying three days ago. The first egg was small and roundish. I thought nothing of the small size because it was the first egg. Then the next egg, which came yesterday, was the same size. Is this going to be the usual egg size, or will they get bigger? Seems like such a small egg for a large-bodied hen. I'm attaching a photo of yesterday's Brahma egg beside a Barred Rock egg for comparison. Any help is much appreciated.
