Sorry to hear that Mel. At least he had a long life. Not many roos are so lucky.Seven years ago I hatched out a bunch of chickens for friends; one that took a long time to work out of the shell the kids named Amy. Amy ended up being a rooster, but he was sweet as can be. He took great care of his girls and a few years ago almost died protecting his flock. Today he met his natural end. A nice long life for a mutt rooster. He was given a proper burial at the farm.
I have had a few late eggs hatch over the years and every single time they were boys. Last year one hatched 3 days late. I just left it in the incubator, never candled it after lockdown, and he hatched all by himself with no issues. He is now a big healthy boy. I am of the firm opinion that if they are not strong enough to hatch out themselves, then they will never be strong & healthy as adults, but that is just IMHO.
