Alrighty, I'm wrong about them not being pure - but not wrong about them being boys.
My marans never came in with red on the wings, but my crosses sure did. But I did look at some Marans breeder pics here and the males do have red leakage in the wing triangle.
Yup, definitely both boys.
Ya know, I always forget to look where people are from before responding. You got through to me with "bloody" though. (my family is Australian, so I'm used to hearing it ) I still don't think they are pure marans with the red leakage in the wing area.
