Back in the spring I got a dozen guinea's. I was out there this morning looking them over to see if I can tell if they are male/female. It looks to me like I have 11 hens and 1 roo. There is only 1 with long wattles, the rest all look the same. Forget trying to listen to them, they all make the same sound.... I never heard the one with the big wattles make a sound. Is this too many hens? Should I try to get another male? I would be willing to re-home some of the females if necessary.
