thats not true for every breed. Some like EE take a little while to develop. Also EE cockerels usually have 3 rows on pea comb, like the one in picture.Hi this is gramma Bonnie. Read my thread, someone just told me the opposite. Pink comb girls, red right away are boys. Will be interesting to see if one is right or both. Good luck. I have several diff breeds of chicks, only two alike. Only my black copper maran is developing a red comb. Hope this is true.
