The rating system descriptions don't quite fit the way I manage my flock. Eggs are expected as best they can be from the breed. We have different breeds though and not all are production breeds. We use artificial lighting to supplement daylight. However, that is not to say we expect an egg from every hen every day. Some last very infrequently. Others are regular layers. No eggs for a long time gets you on the naughy list, but it doesn't mean death row either.
