Extra eggs

Hello! I have 13 laying ladies that are approx 11months or so and for the past 2 days I’m getting 15 eggs. And I collect daily and I know for sure I didn’t miss any because last night we cleaned the coop out and there was zero chance of missing an egg and today there was 15 eggs. And 2 of them are smaller than normal. Is it possible two of my ladies are laying 2 eggs a day?
