I have a 5 1/2 year old rooster that is not preening his new growing feathers. Occasionally he makes the motion to preen but he doesn't actually touch the feathers, rather he's preening in the air close to the feathers. He does the same motion in the air if you touch the feathers that need preening (still in feather casings.) My guess is he's getting too old physically or mentally to preen properly. But is 5 years really that old? Has anyone seen this before or offer any reasoning? I've been helping the old guy out, but rather he'd take care of it himself!
