I have three hens currently, two Rhode Island Reds and one easter egger. I usually get about two eggs a day, one brown, one light green. I know for sure one of my RIRs is laying. She is always sitting on the nest. Obviously the EE is laying as well. But I would think with twice as many RIRs we'd get more brown eggs than green. Maybe not twice as many, but at least the majority would be brown I would think. I've never seen my other RIR (who has a very slight cross beak but otherwise seems very healthy) on the nest, ever, and no indication that she's laying. But maybe she's a ninja egg layer and I've just never noticed the signs? She's kind of mean and I don't really like her and am planning on getting rid of her after we get a few new chicks this spring, once it's warmer. Basically I'm keeping her around for body heat. If I had any evidence that she was laying, I'd consider keeping her. So, short of separating her from the others (which I really don't want to do while it's February anyway) how do I figure out if she's laying?
