I have 14-15 standards that should be laying and at least 10 bantams. I get anywhere from 2-6 eggs a day, with 10 being the most I've gotten in one day about a month ago. I can't believe cold weather affects them so much, at least thats what I hope is making them not lay. Although, not quite sure what I am going to do with 25 eggs a day lol.
My Exchequer is the only one that I know is consistently laying. She's my only white egg layer and she only took time off to molt. The rest must draw straws or work out a deal amongst themselves as to who wants to lay on that particular day.
