Tail feathers are completely irrelevant at this age. Saddle feathers start coming in around 12 weeks on most boys.
Oh boy.. you better teach that young man some respect or you're in for a world of frustration.. Handle him on YOUR terms, not his. Walk through him and make him move out of the way... I'm NOT a fan of dominance training and don't consider it effective. But I am hugely a fan of having balance minded roosters. Teaching them a healthy fear equals respect in the chicken world. Look for ways to not challenge him and also not be seen as part of the pecking order.
To make it easier to get a hold of and have him used to being handled... start doing so shortly after they settle onto roost in the evening. If he pecks you as you approach.. give a little poke or slight peck to the top of the head and slight tug to the feathers on the back of the neck.. Speak some of his language. Again not becoming a part of the pecking order or seen as an aggressor.. just not tolerant of any antics.
Consider rehoming or allowing him to feed someones family, Wyandottes are quite tasty.
For me an OOPS rooster is not a good enough reason to keep one.. and it can be very challenging.. completely changing your chicken experience. Decide what is best for YOU and your flock.
I don't consider roosters as flock protection. They are just front line sacrifices facing most predators I have. I do keep them for eating and breeding. And a good rooster (not still maturing cockerel) is a valued asset for his role in the flock!
It's a very personal choice, not to be taken lightly. But what an adventure!
