I have 11 golden comets who have layed like gangbusters since 15 wks I feed laying crumbles free choice 24/7. We started giving them fish from my sons fishing every day. We watched the eggs increase in size. But didnt really conect it to the fish. Just knew the extra protien was good for them. The only slack we notied in laying was with the decrease of daylight so we added light in the morning and production was up again to regular 8-11 eggs a day for 11 hens. Since it has gotten cold and no fish were coming in the production has not stopped only dropped a little, but the eggs decreased in size and began having dark bumps and spots on them. After the guys started deer hunting the trimings were going to the chickens. Now the shells have cleared up and the eggs are huge again. I guess the 16% protein was enough to lay but not to get the quality and size during the cold weather.
