I just love the way they look pecking around in the green grass, all sizes, colors, ages...its so peaceful. I have been adding babies, new hens, cockerels...no problems so far! There are even a couple of days old babies in this mix, following the mom. I do have a few older roosters outside the main enclosure, kind of free ranging because they were getting too rough on the girls. I have noticed how my cochin bantam roos seem to court the new girls, very gentlemanly while some other roosters chase them like bullets lol but to be fair the cochins roos have also showed their bullet like persistence with my older girls. Anyway, just loving my birds...my buff brahma (a fantastic mom, seen in photo) brings the babies to me for treats, and they are beginning to eat out of my hand and lose their skittishness. I have 2 other beagle mix dogs. They all look after the chicks.
