Hi Shanda, welcome to the forum. Glad you joined.
Do you have a rooster and nine hens or do you have an immature cockerel and nine immature pullets? Their maturity level can make a big difference. Most flocks that consist of mature roosters and hens are pretty peaceful but flocks of immature cockerels and immature pullets can have a lot of drama. Mature flocks can have this kind of problem too but it is a lot more rare.
Something else to consider is that some hens have brittle feathers. No matter how gentle the male is feathers are going to break. If it is anywhere close to nine out of nine though I don't think this is your problem. It's probably the male. If the females are resisting they are not helping but I'd still blame the male.
If he is an immature cockerel and they are immature pullets they may grow out of it, but if he is making them bleed it is dangerous now. You need to do something. If they are immature, lock him up by himself for a coupe of months. Then turn him loose and see how it goes. You may have to lock him up some more if it doesn't work out. If he is a mature rooster, either get rid of him or lock him up until he dies of old age.
On a certain level this isn't that unusual for an immature flock, but if he is making them bleed that is beyond acceptable limits.
As an aside, don't believe in that magic ratio for hens and roosters. As you can see they don't work.
