The size of spurs and the red waddles on it's face say alot for a pheasants age as they would have to be at least a year old for the waddles. For as far as the lines on the tail I have never heard tell of it. The tails can very in size due to predators and other pheasants fighting with them. So my guess is that the lines on the tails have little to do with it. Here is an adult pheasant showing off to a hen in my pheasant pen. I raise them here for dog training and release to try and bring some around here. This one is a breeder.
