Just remember that the commercial breeds that lay so well are kept in climate and light controlled conditions and are fed a very strict diet. I am not arguing that they are great layers, but there is more to it than just breed. It is also how they are managed.
Many people have chickens that lay one year throughout the winter, but the next year, they don't lay during the winter. Pullets often lay throughout the first winter without going through a full molt. Unless you manage the lights, chickens over a year old will almost cetainly molt when days get shorter, which means they really cut back or, like mine, totally stop laying until the molt is over.
Severe heat of severe cold can cause chickens to reduce laying. The lights are on long enough for them to get the 14 hours of light they need but not any longer. And what they eat is very strictly controlled over that 14 hours.
Unless you manage the chickens like the conmercial operations, controlling lights, climate, and diet, even the great commercial strains will probably not produce as welll for us year round as they do in the commercial operations. I fully agree, they will lay a lot of eggs.
