My Golden Comet pullets are only 17 1/2wks old. A couple started laying the first of the month at 15wks and more of them have joined in. I have 11 pullets and I got 7 eggs today. Wooohoo! Of course the eggs are small but they are supposed to have big eggs later. I have already gotten 3 double yokes too. I could not be happier with them.
