My sex-link is a "Golden Comet" from the local feed store. She started laying jumbo brown eggs with a few speckles at 20 weeks old on Sept 25, 2010. She hasaveraged 6.6 eggs per week ever since. In December she twice laid two eggs in one day.
She's very friendly and less apt to roam like the other three breeds I have (EE, BA, SLW). She's a moderately good forager compared to the others, i.e., she's not as aggressive at scratching and picking up bugs and worms, and she's one of the first to hit the feed tray in the morning. She's always looking for treats from people, too.
She's been in a light-medium moult the past three weeks, but hasn't slowed laying at all.
If anyone goes broody while the feed store still has GC's, I want to have her raise two more day-old GC chicks for my little flock.
