I have 2 Red Star, 2 Buff Orpington, and 2 Barred Rock.
The Red Stars both started laying in their 16th week, and one of them lays double-yolked eggs a few times a week! I'm afraid that means she will stop laying that much earlier. :(
The Buffs and Barreds all started laying in their 23rd week...
We are putting the finishing touches on our coop, building an automatic door, and finishing the run. I am anxiously awaiting the arrival of our first pullets.
