I have two Americanas and one Maron hen. I find they don't lay very well. They have turn two years old. I have had red rocks that lay really well. How many eggs would I expect to get from them. They really haven't layed well from the start.
My black Copper Marans is 11 months old, gives me 4 or 5, mostly 5 eggs a week. Did you say your hen was two..she just may be at the slowing down time.
I'm not getting any eggs. Today I found an egg on the Poop board from the Maran, I don't think she has laid in weeks. I have a light on for them over this winter, they just are not laying much at all. I had red rocks the laid well, they got old. I have checked the yard to see if they are laying somewhere else. I have a silky that continues to get broody, I wonder if that is stressing them out.
