I have a 1 1/2 year old gray that shaves off half of each feather - I
believe it is the inside half so you can't tell when she is just
sitting. But when she flaps you can see what she has been up to.
I am offering all the toys she enjoys and rotate them to keep her
attention away from her feathers.
I am trying to keep her busy with other activities so she leaves her
feathers alone.
