The strangest thing is neither the CCLs or the Marans are noted for broodiness. They will go broody but for the Marans it's often later in life and for the CCls, I don't really know.
Fret, the hen in the picture has turned into a broody monster.
I agree. Meet my 5 year old Marans broody monster, Mocha.
She is giving me the stink eye in this photo because I just removed her from the nest box and placed her on the roost. She has just recently started back laying.
