Of the ten chicks we ordered, three are BOrps. They are all now 7 weeks old. One is very easily identified as a roo. Comb is twice if not 3 times the size of the other two. He also is developing the pink waddles underneath. One of the other ones is most definitely a hen. Her comb is still yellow and showing no signs of waddles. The third is somewhere in between. The comb is about halfway between the other two in size and color and has very small pink spots for waddles. Looking at photos online it looks like BO hens also have some pink waddles. Is this correct? And what would you all think about our third BO roo or hen?
