Alas, my rooster and I broke up...

[KCD]

My Rhode Island Red cockerel had been the friendliest, nap-on-the-lap buddy of my flock of 14 chicks. But as he turned 15 weeks, he suddenly started pecking me viciously without provocation. I wasn't holding him or reaching for him. None of his girls were squawking or stressed. He just walked up and pecked ( pinched and wrenched, like trying to rip a piece off!) my arm long and hard, to which I patiently responded by petting him gently and saying soothing, forgiving words. Then he tried to rip a chunk out of my bare foot even harder, little brat! That same day he started the first fight with my younger 10-week-old Barred Rock cockerel. Alas, his warlike genetics, prompted by hormones, have kicked in, despite all my cuddling since his birth!
I only want one rooster for my 12 hens, and I purposely searched far and wide to buy the Barred Rock cockerel chick (I want to breed some Rhodebars using him and my RIR hens). The RIR cockerel was bought as a pullet, wrongly sexed. He is already magnificent looking, has been crowing for 2 weeks already, but is now tending to the aggression this breed of rooster is known for.
So my dilemma: Shall I keep him 4-5 weeks more until the Barred Rock cockerel develops his temperament to see which is nicer? Or Is my 15-week-old, much larger, combative Rhode Island Red likely to kill my smaller 10-week-old Barred Rock cockerel?
And also, can anybody predict based on their own roosters, whether the Barred Rock will likely be less aggressive than a RIR?

Our barred rock rooster was a complete turd and we ended up getting rid of him. He continued to be a turd at his new home and was culled. Our neighbor got a barred rock rooster for her flock and he attacked her grandson. I was talking to a guy at the feed store and his worst rooster was also a barred rock...so 3/3 barred rocks were trouble, but I can’t say that’s always the outcome, just my experience.

I have to say I've heard this from others, also, one lady saying Barred Rock was the meanest rooster she ever had. Well, my RIR cockerel is living at the neighbors, I have a huge new Bielefelder that is soooo gentle with the pullets and me. So we'll see whether this little BR gets nasty and has to go, or whether the bigger rooster will make him mind his p's and q's!

Ah, you are the one who left me the tip about Bielefelders! Thank you SO MUCH! I researched them and went out and bought a one year old rooster who is the prettiest rooster I've even seen/owned! Also two unrelated 3 month old pullets! I am delighted with them. Both were hatched from Murray Mcmurray eggs. Here's what I posted about them: https://www.backyardchickens.com/th...k-rooster-for-my-flock.1477975/#post-24627378
But I'll say now on the second day, the rooster made himself king of my flock of 15 without even a serious fight with my RIR cockerel, is on constant guard duty, alerts the girls to yummies, told my hens in no uncertain terms to leave his two girls alone (I could integrate them the very first day!), is a gentleman with the younger girls who rebuff his advances, and is not one bit aggressive toward me!! Where has this breed been all my life? I'm so delighted having found them!!! Thanks again....

Awww thats awesome! I’m glad you took my advice! I still love mine.

I also really enjoy Buckeyes. Similar to a RIR but much more “tiny dinosaur” like. They don’t lay as good as RIR but their eggs are similar in size to Bielefelder.
