could any one tell what sex these may be ?

The first and last ones are cockerels. I'd need to see the chest and the comb from straight on to guess on the wheaten.

The 3rd one is a pullet. Wheaten Marans are easy to sex visually. All the girls feather in that salmon colour, boys will feather dark. Much like Salmon Faverolles

thanks for all replies, i was thinking with the wheatons light female,dark male.
the 1st + last, (copper blue & the dark wheaton are always staring each other out before they pounce on each other, its funny to watch) so i presumed they might be cockerals, couldnt guess at all on the cuckoo maran.
thanks again
