I have 3 BO's. They are now 6 weeks old and I'm wanting to sell the roos but I want to make sure of which ones are actually roos before I sell so can you help me. I was also wondering what is a good price to ask for them at this age. I haven't really seen a lot for sale at this age so I have no idea what to ask. This one I'm pretty positive is a roo. I'm pretty sure the one on the right in this picture is a pullet but I'm not sure about the one on the left. It's right between the other two in comb size and it's a little bit pink but not as much as the one in the above picture. So I'm just not sure.
