I've been keeping an eye on the nest boxes in the morning, but don't always peak around the corner where the feeder and waterer are hanging. I went back there this evening to shake the feeder and voilà, there were two brown eggs in the back of the coop. They should be from the Golden Comets, which they say can start laying around 18 weeks. Today is exactly 18 weeks since the chicks were shipped. Being the first ones, they're kind of small, but should get to be large eggs in time.

Next to a few large white eggs.
