Hello All, I have only found one thread that asks about chicks or chickens shaking their tail feathers. I have two chicks, now almost 6 weeks old, and for a time I was worried that one might be a cockerel. Henrietta, the chick in question, seems to be showing signs of being a pullet, but she also does a tail shake, where she shakes her tail from side to side rapidly. Does anyone have pullets or cockerels that do this? Is this a characteristic of gender, or just a funny behavior?
