I have 8 hens, half born in June, half born in July, and the older ones are on the verge of laying. They're not really showing any signs other than wattles coming in, and combs changing color. I live in the mountains. We've already starting getting occasional light snow. They are a mix of breeds. Is it too much to hope I might get eggs before winter? If they do start, will they stop again and take a break when it gets really cold?
