Many people say animals do no have personalities. I know when mine are happy or sad. They are non stop laughter, even when they are trying to be serious.
I let my one smaller chickens out to forage today. Not an easy feat with ice patches but they still love it. They are out doing happy dances and I think having races.
My other older chickens are having special snacks today and are they ever happy!
My one muscovy greeted me today by the front door - a no no. Too close to a road. I took her back down and gave her a special reward after a backyard mini walk. I didn't want her to associate a treat with being by the door. Every morning she talks to me for about 3 minutes when i start doping the animal rounds
And once in a while I get a mean or grouchy animal. They quickly find a new home of join us for dinner - not in there way they could appreciate.
