Old Hen Coop, Young Hen Coop

[what did I do]

I have a coop of old hens and a coop of young hens. I've been finding small light colored eggs in my old hen coop. My old hens lay darker eggs very large eggs. All my chickens free range together. Could these small, including 2 fairy eggs, be coming from my young hens? The eggs are all laid in the old hen coop. I have not seen any young hens in the old hen coop. Occasionally I have seen the old hens in the young hen coop. I do have a broody hen and one we just broke from being broody.

My Barred Rock hens would be the first to lay - hatched @ march 20th. The eggs are a light brown like a barred rock's.

My guess is it the young ones. Unless your there from dusk to dawn they can sneak in, especially with a couple of the same breed in both flocks. Could be wrong, the elders could be getting ready to go into molt and laying odd eggs.

I guess they are pullet eggs. I found a California White going back to sit on her little egg.
