Black Copper Marans showing at Four Weeks?!

[TwoChicksChix]

Hey everybody,

So this is my first time with BCM and I hatched out four of them about four weeks ago.

Well, even right now they’ve started to show wattle and comb difference and I think I have one boy, two girls, and one unsure.

I have some pictures of each:

First girl

Second girl

First boy

Unknown (thinking boy)

I guess I have two questions then.
1, do those seem like correct guesses so far? I know they’re super young, but it’s just a guess.
2, do BCM show so early? I’ve never had another breed I could guess at this age.

Thanks for any and all help.

Looks like 2 girls and 2 boys to me.

For my marans they did show little more early. You can also tell boy from girl by the rate of their tail feather growth.
Your boys have such short tails compared to the girls.

Also I noticed that my maran boys are a lot “chunkier” than the girls at that age

That’s what I figured, based on wattle length, comb color, and tail size. I’m just amazed they started showing so early. I mean, they’re only a month. I have some chickens that are four/five months and I still am not sure if they’re boys or girls.

Lol, these guys are helping me out.

I had some self blue cochin bantams showing at less than 3 weeks old. It's crazy how soon they can distinguish themselves.
