I have a 6 week old Barred Rock, a 5 week old Light Brahma banty, and 5 week old Black Silkie. I had thought that the Rock was going to be a roo, it being aggressive and protective of the other two. But last night I went to check in on them after dark, and that Rock had a banty under each wing! They both stuck their heads through to look at me, it was adorable. Is this a motherly thing, or just a good buddy for warmth?
