I have a flock of 9 guineas mixed with 15 hens. The guinea have always foraged together. This past week one guinea hen has started hanging back in the coop with my broody hen. She sits on top of the nesting boxes most of the day. She's only 6 months old but is she thinking about laying? Should I just go ahead and create a concealed spot on the ground for her to lay just in case? On a side note, I think I have 4 hens and 5 roosters. If I have instead 5 hens, is she just odd girl out?
