Yeah, looking back at your most recent picture of Sunni, I would lean more toward cockerel at this point, too. :/
I always thought with Easter-eggers that the tail feather length indicated male from female, since the two EE boys I had before had almost no tail feathers for weeks. I'm pretty sure Hika Ma is a boy at this point, though, and he got his tail feathers in early, so I just don't know anymore on that.
Like I said, though, Easter-eggers are tricky! I've even seen one with all the sure signs of being a boy turn out to be a hen after all. You just never know.
