I caught 3 of my little week old chicks scratching up the shavings like mad. Then they stood together picking at and arranging the shavings. Then they stomped them down a bit before they wiggled and settled into place in the soft comfy little "nests" they had made. Any chance this means these three might be female? If they are is this an indication of strong mothering instincts? Since mine are streight run I am always hoping to tell at least a few of the hens. Also one of the people interested in taking of few of the extras off my hands wants them for broody hens so I'd separate these out if it might be worth the effort. Any one who has experience with breeding and raising poultry please chime in.
