My Buff Orp babies are about 7 weeks old... Cute huh? Anyhoo, I'm starting to see some new behavior from them and I'm wondering what it means. It starts with a shivery type of head shaking and ends with them sort of charging each other or one of the chickens. It looks a little aggressive but they're not otherwise aggressive and have never nipped at me. And the shiver/charge has never included biting or anything like that so I'm a little confused. And they only seem to charge someone when their back is turned, kind of like when a rooster courts a hen, could this be a male thing? Do I have two little boys?? I know pretty much all of the chickens body language but ducks are totally new to me. Anybody with duck experience out there know what I'm talking about?
