Quote: I am happy to help.
The egg laying ability of the Hatchery RIR is what nearly drove the Heritage RIR to extinction. They lay earlier and lay more for the first two years. After two years, The lay rate drops very quickly. This characteristic is why the Commercial Egg Farms cull the hens after the second year.
The Heritage Reds will lay over a longer period of time, so they actually will lay the same amount or more. The take away for the Back Yard Chicken owner is if you have the hatchery type of chickens, you will need to either live with less eggs sooner or replace your hens every two to three years.
