I have a question. I have 5 hens in my coop. 3 blue Orpingtons and 2 golden comets. All were sold to me as such and I didn't get them from a hatchery. I have always heard that Orpingtons lay light brown eggs. Well, I am getting two colors out of my girls. Large dark brown and very small blue/green/ gray eggs. The large brown are coming from my comets. Does this mean my Orpingtons are actually crossed with another breed? They also don't lay as well as I thought they would. They are 1 year old and I've maybe gotten 10 or 15 eggs out of all 3 of them.
