I have a pair of booted bantams, as shown below. Now, clearly my hen is a black booted bantam, but I'm not sure what the rooster is. Also, can their coloring be sex linked? I originally had two roosters, they both had the same coloring, and I'm noticing that, in my first batch of BB chicks, two of the chicks are developing the same coloring as their father, and the third one is still all black. They all hatch the same color; black with a white chest. I'd just like to know so that I might have an idea of what gender they are when I sell them in a couple weeks, when they're 8 weeks old. Thank you!
