I'm a rooster fan, but I'm also a realist and while I agree with most of what you've written my experience of what roosters actually do when the shit hits the fan is rather different to your description.I think a rooster is a good idea when you free range hens. Their job is to prote t their females so they are always in the watch for predators and when they see one they alert the oblivious hens so they can run for cover! Def a good addition for flock safety and they are a so called speed bump because they will take on whatever is after his hens no matter the size and even possibly be killed in the process all while his hens run to safety. What a guy!!! As for which one to keep I wouldnt want the super aggressive one so try the take one and see. I love to hear my guy crow! My oegb is first with my son but not with me ever. I dont allow him to get away with it so if the roo starts wing dragging your daughter or being showy in any way she needs to pick him up and hold him for a few min and rub his waddles. Roosters came be tamed down without showing them who is boss so to speak. Picking then up shows dominance is a kinder way. I read all this on an article I found here on byc just dont remember the name but the info is worth its weight in gold! If stew pot is last resort then the bright side is that his life wasn't wasted he just became part of the food chain. That's life. Some roosters are born mean as hell and it takes a lot of blood sweat and tears to frame them and daily work that some people just dont have time to do. I had a rir roo that you couldn't get near without a stick and he was that way his whole life no matter how nice I was to him or how much he was held. So that's my experience. Free roaming the hens will pick up swiftly just make sure they know where to roost at night so cage them atkeast 3 weeks. That's what I do. If I catch mine qhere theh shouldnt be I tell them to get home and walk them out of the woods. They have figured out what my commands mean and we do well! Good luck
I've had lovely roosters, good with the hens, good with people but when that hawk comes hammering towards them, they run for cover. I don't blame them, discretion being the better part of valor, as some see it.
The best all round roosters have always been the difficult ones. No you can't give them cuddles and if they don't know you they will charge you down but they were prepared to die for the hens and didn't seem to care how big the threat and that of course includes humans.
It seems some people want their roosters to not be afraid and aggressive towards everything except them. That's a very hard thing to ask of any animal. If that is what you want then you need to put the work in to get it.
