THanks, all!!
Beth, I'm trying real hard to tell by the saddle and hackle feathers, but I'm just so new at this that I don't know what 'pointy' looks like. Lol. I've only had chickens for a year and all mine are hens so far.
The black ones to me look curved - like our other girls. And that one acts like the other girls. The white one I have seen sort of facing off with one of our other young ones (a few weeks younger than these guys)... None of the others did that. Not sure if that is just pecking order order stuff or if that was rooster behavior. Again, I'm just too green.
The white ones do look slightly pointier to me, I think... Here's another photo where I think the hackle? feathers might be pointy.
