Silkies lay smallish eggs and are fairly winter hardy as long as they have a dry, non muddy coop. Although, they are perpetually broody and just a tad snuggly, they may end up being "house chickens."
If you want small eggs, seramas have the cutest bite sized eggs. But they are not winter hardy and will have to have a place in your garage or sunroom or whatever may be attached to your home. Last year mine lived in the laundry room in a recycling bin during the evenings and a blocked off space in my dining/living room with washable wet pads. But they were babies then. This year they have a mini coop in the garage.
