I would be inclined to agree. Amount of daylight, regardless of temperature, will suppress laying. Some chickens will even put off beginning to lay if they come to maturity around the winter months.
I would recommend doing a bit of research before adding artificial lighting though. It will undoubtably bump up laying during the nonproductive months but I've read that it can also lead to shorter productive and life spans in the hens.
