Here is one of the chicks from the 11 my broody Little Hen set. As you can see, it only developed head, cape, wing & tail feathers. After 8 weeks there was no sign of body feathers coming in and the down was getting worn away. You can see one of its clutch-mates in the foreground that was properly developed. I culled it along with my Roo's this morning. Is this a common condition?
