We have two backyard chickens, and we adore our girls Ruby and Julianna. We had a rooster that was hatched in my daughter's first grade class, but when he turned out to be a rooster we had to give him to a friend on a farm because we are not technically allowed to have chickens in our subdivision, and I think the crowing would have pushed things too far.
Anyways, Julianna started a new thing lately, when I walk by her, or feeding her, she stoops down and raises her tail feathers, like when a rooster jumps on a hen. I pet her, and give her a little back rub, and afterwards she ruffles her feathers looking very pleased :-). What a funny girl. Has anyone else seen such behavior?
