My 12 pullets (can you believe I got 100% correctly sexed chicks), 4 buff orpingtons, 4 barred rocks, 2 rr reds, and 2 e eggers, are now exactly 6 months old today. No eggs yet and I'm getting impatient...I figured they'd be laying by now. Yesterday one of the barred rocks let out a big "BRAAAAAAAAAAAAAAAAAAAAAAAK!" and I ran out expecting to maybe find an egg. Nothing except an egret that had landed close to the coop and upset some of the hens. Am I too impatient? Could the extreme heat we've been having have an effect on egg laying?
