You are correct, I am not a big fan of the looks of guinea fowl. I have them purely for practical purposes. They eat a lotta ticks, the keets and the adults sell well. People expect them to be ugly. My ignorant customers however freak out when they see a naked neck, because they have a different image of a chicken. They don't expect a chicken to look ugly and bald like a low grade government clerk. So they will not buy them.
They don't know what they are missing! Even if I wasn't selling some of mine, I would still keep them for myself.
