Hey All, Love the site, really informational. I have a flock consisting of 2 Plymouth rock hens, 2 New Hampshire Red hens, and 2 Helmeted Guineafowl. My flock is normally let out during the day and allowed to free roam around my backyard. When dusk approaches or when night starts to fall, the flock resides back into their coop with no problem, with one exception. For some reason one of my New Hampshire Reds will not follow the flock. Instead she roosts within a large pine tree i have in my yard. She roosts on top of a branch above my head and I have to grab her and put her in the coop. I am afraid of predators and would like my hen in the coop at night with the flock. Has anyone experienced something similar to this behavior? How can i get my hen to follow the flock when its time for sleep? Thanks all.
