16 week old comb size - chicken or rooster?

[Sillyna511]

My chicks are 16 weeks old now and I am still paranoid that one of them is going to turn out to be a rooster.
This girl’s comb is recently noticeably bigger and redder than the others. They were all pretty similarly sized until this past week when this girl’s has grown a lot. You can see one of the other girls behind her, with a comb about half the size.

Would it be much bigger than this by now if a rooster? Does this still look like a female?

Obviously I’m brand new and these are my first chickens so I’m questioning everything.

She's going to lay soon.

Those are huge and very colorful combs/wattles for 16 weeks. But I am not seeing male specific feathering at all.

If they are purebred barred rocks, the coloring is also female specific, being single barred rather than double barred.

Congratulations, she's gearing up to start laying! A pullets comb will turn red right before they come into lay, it's nature's way of advertising that they have reached sexual maturity.

Okay so it sounds like this is still within normal female comb size… That’s a relief! It just looks so big I was scared she was a boy. We did just open their nesting boxes for the first time a few days ago because we know they’re reaching the age that this breed normally starts to lay- so I’m very excited to hear that she is getting close. They have all turned brighter red over the last few weeks- the others just didn’t get so large.
