So far so good. Now that he is mostly done with replacing the body feathers, all will be channelled towards the growing of the flight feathers. The flight feathers of the tail are doing great and flawless so far. If all is well, the longest pair of tail feathers should be no less than 14 inches. I would very much like to see this pair of feathers growing out nicely and overlapping all the way, as they should be.
