I have a flock of seven, five of whom I've had for a few years. I got two chicks from a feed store at the beginning of October. One is a very sweet and BIG blue Cochin. She started laying about a month ago, and I am perplexed because she is laying perfect, little bantam-sized eggs. I've experienced "pullet" eggs, but I don't think that is what's going on here--these are consistently small eggs that look nearly identical to the eggs laid by our bantam Cochin (but one's light, one's dark, so I can tell them apart). She's the biggest bird in our flock . . . why is she laying such tiny little eggs??
