Hi! I have three Silver Laced Wyandottes that I got at 3 months old. They are now 5 months old. I also have full grown Sex Links. My Sex Links have wattles and combs, are hens and are laying. My Wyandottes have not started laying yet, have wattles and close-to-the-head combs. One of my Sex Link girls "crows" sometimes. I have read that this is normal. Today, "Raquel", one of my Wyandottes crowed several times. Uh oh. Is Raquel a roo? Or is she just making noise? One of the three Wyandottes is one week younger and has NO comb an NO wattles. The other two do. Opinions? Help, help, help!
