I was quietly picking the last of my blueberries when I observed two of my chickens giving each the stink eye, holding very still and then all of a sudden both their neck feathers burst out and it was obvious that they were about to attack each other. So I did the only thing any chicken farmer would do, I threw blueberries at them. Alas it appears that "Sarah Jessica Parker" my feather footed hen, named for Carrie Bradshaw's lovely feather shoes in Sex and the City should have been named "Big." Damn. My chickens are 14 weeks old. Other than this behavior I am just not sure. The two in question are very different breeds (Leg Horn and Bard) and the Leg horn is much bigger. Any suggestions to make a final confirmation?
