I've heard that you put a little cheyaene or hot pepper in the feed. It is supposed to get most any hen to laying. I haven't tried it, but plan to start todady.
I got 10 eggs today...20 hens. I took this pic of my carton of "Jumbo" eggs. The one at the back is 3 1/2" high! My hens are Red Sex-links and Buff Orps.
We got a blizzard this week, so having trouble with frozen eggs.
