Definitely splash cockerel. Blue looks girly to me at this point, too. The blacks seem boyish, but only because the combs are really up there, but I'd wait and see a bit longer on those.
It'd be a miracle if I ever got my splash pullet! The splash roosters are impressive, too, but I dont need one!
Could be wrong but I say one of each on the blacks. Of course as you may have read I had a late bloomer I thought was a hen till he was four months old.
