Sexing 3 week old chick

[we5farmers]

I have a crossbreed chick who is now 3 weeks old. I’m wondering if it can be sexed. I originally thought the Momma was my Australorp but because the chick has feathers running down the side of it’s legs I believe momma was one of my Marans. Daddy is a Barred Rock or Barred Rock/EE cross. Can anyone give me a little help sexing at this age? 1st picture is 1 day old. Other 3 pics are today. Thanks in advance for any help!!

Thank you for the reply! I was afraid of that. I can’t keep another Roo. I thought maybe too using Barred Rock sexing tips but wasn’t sure if they would be correct because it’s a cross. What makes you think Roo, if you don’t mind me asking? I’m still new to this and would like to learn.

That's a larger redder comb and wattles than I'd expect in a pullet of that age. I agree, cockerel.

Yup the reddish wattles, watch for the hackle (neck) & tail feathers soon will show up too.

I agree with the others. The developing red comb and wattles are the giveaway.
