I think it can depend on the breed as to how fast they feather in fully. Our light breed boys have been fully feathered by 5 months old, but a larger breed may take longer.Now that you say it, I feel kinda naive. I think I was in shock that he had not sacrificed himself to save the damsel in distress
But mostly I just wonder what the heck happened. How did he end up in the front yard?? How did he even get over the 6' privacy fence? Why did he not run to the coop? To my defense I was still kinda loopy from the anesthesia that morning and it was our first ever predator attack so not a great combination to say the least. Hahaha
But you are correct, I want a rooster for an early alarm for the girls and a pretty bird for me. Not much more I can ask of him. At least he's got the second one down. Still lots of time to work on the first. He is only 18.5 weeks.
BTW, when is a rooster fully feathered out? Like, all the tail, saddle and hackle feathers.
