Aggressive rooster toward hens

[Bano]

two of my white Jersey giants have missing feathers on their back. One of them badly to the extent of bleeding. I’ve been watching my flock and I don’t see any hens picking on them. The rooster is very aggressive towards them (and me). I’m suspecting it’s him! I think all the pricking is happening inside. The roo is RhodebIslamd Red. (I have three jersey giants, two cuckoo marans, and two other RIR). They are all 8 months old. This is my first time and I’m worried these two white chickens will be picked on to death.
Also, one of the RIR keeps leaving the flock(she jumps above the fence and roams around the house). She used to also be picked on by the rooster I think. What do you advice me to do?
thanks in advance

Oh wow so um...... The Roo may just be mounting too much. I would seperate him for a couple days and get some cloth to put over the hens wounds and put blue coat on the wound as well (chickens go CRAZY when they see blood on another bird) and just watch it

What do you advice me to do?

Separate the male immediately...maybe forever.

How big is your coop and run, in feet by feet?
Dimensions and pics would help immensely here.
