I've had this chick since it was 1 week or less. It grew it's first feathers at about 2-3 weeks old, it has two fleshy bumps on the wings in which no feathers grow, has a lump above the vent and the wing feathers are scratchy. It was raised with another chick, which is very healthy and fully feathered, so I know I didn't do anything wrong. Here it is now, at 9 weeks old. And the chick it was raised with.
