What is often cited as the trade-off for the high laying output of Red Stars regarding their lifespan?

Answer

Their productive life is often shorter than heritage breeds, declining after two or three years.

Because the birds are bred for intense laying output in their initial years, this high performance comes at the expense of overall longevity, with production often declining notably after two to three years.
