I have read from more than one person that guineas mate for life. I have in one pen 8 guineas; looks like 3 hens and 5 males (need to move 2 of the males). In another pen, I have 16 guineas; looks like more hens than males. The 16 fight a lot, it almost looks like I need to separate them by color. I hatched and brooded all of them together. I moved all of them into a pen together, however, it looks like I am going to have to separate them. Problem is, if they mate for life, how do I do this? All suggestions appreciated. I would like for my eggs to be fertile.
