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!!
