I have 4 red sex linked hens 2 production reds and 3 RIR hens. With a blue cooper Maran rooster. All about 6 months. I get about 4 to 5 eggs a day and the past 5 or 6 times I collected eggs noticed that one of the eggs was a different color it was almost white. And it is also a lot smaller than the others. Is this just because it could be one of the hens just started laying or is it the breed?
