What do you all think of a rooster who chases hens and grabs them to mate against their will?
.. Popcorn is about a year old now and still doing that.
I have 16 hens between my 2 roosters and Biscuit my main rooster is always good to hens and people but doesn't fertilise (does mate but not fertile anymore for some reason) so that's why I have brought in the 2nd boy about 7 months ago who does the job of fertilizing, but stresses the hens chasing them down

What do you all suggest I do? Keep Popcorn and hope he gets better treating the hens? Or try find a new rooster to join my flock?
