just don't let them sit. nearly all mine are in moult anyway after trying to sit so am down to 2/3 eggs a day from 10 hens-although most of mine are 2-5 years. Some will lay a bit before winter, some will not. this is where I have to big up my Minorcas, never go broody, lay most of the time around the year, quick moult and a handsome pure bred. The Scots Greys and Marsh Daisies, while lovely, are not that productive in comparison.
