She is growing close to the maximum rate for a yearling green. Greens are typically 4.5 to 5.0 feet at one year of age. Exceptionally large ones can be 6.0 to 6.5 at one year even without power feeding although this is rare. She looks really healthy, and just be sure to back the feed off a little in the third year as they are prone to get over weight on a heavy feeding schedule starting in that third year of age. Great job with her.
