My first time hatching eggs... Is this 15-week-old chicken a male or female?

I hope you are well! We hatched seven chickens successfully, and thankfully no issues with predators so far. Some of the females were obvious and some of the males obvious, but I was a bit confused with these two. The gray ones head looks more like a female, but the tail feathers look like a rooster. Can you confirm which it is?

Also, this black one's head looks like a male, but the tail looks like a female. Could you confirm what the black one is? Thank you for your help! I am having so much fun raising these chickens

Both cockerels. Giant red pea combs and wattles, waterfall of pointy saddle feathers, and the patches of color over the shoulders are all giveaways. both handsome boys.

Both cockerels! Your one "hen tailed" cockerel could be part Auracuna, and that's why its so short.
