Chicks male or female

[2ndTink]

My chicks are a bit older now. How do you know if they are male or female at this age, they are 5 weeks. Also, they are getting feathers so they look scraggly.

The ones that have the largest combs at this age (the chick in the first photo) and the light colored chick with the red on its shoulders are my initial cockerel guesses. They are still young, it's easiest to tell for sure in the 12 to 15 week old range, but it's fun to guess before then.

Gotta love the gangly stage some will move gracefully through and continue to feather quickly, and others take their sweet time replacing their fluff.
