Hello! My Light Brahma's are going to be 9 weeks old in a couple of days and I am so confused about their gender. Our LB Tulip has feathered in super slow compared to her/his sister making me think Tulip was a roo? But now I am not so sure because he/she is not getting a red comb or wattles? They are hatchery stock so they are really dark for LB but still beautiful to me! So what do you think I have?? IRIS TULIP Thanks!!
