Hens pecking my rooster

[SoAzChick]

I have a rooster that I rescued. He was originally rescued by my sister-in-law when he was running away from a pack of dogs and he ran into her open patio door and under her bed. Unfortunately for Foghorn, SIL doesn't have chickens so I agreed to bring him home. His plume was completely ripped out. Chickens keep plucking at his back not allowing any new feathers to grow in. How do I stop this behavior? Usually, it's the other way around, with roosters plucking at hens feathers. Also, the chickens are not plucking each other just Colonel Sanders.

Rooster Booster makes a “pick no more lotion.” Once skin is exposed your hens will continue to peck. You could try giving some higher protein food (20%-24%) so that he can grow in his feathers. If you can separate him until he grows his feathers back, that would be even better.
I had a similar experience, however my rooster grew up with my hens. He just hadn’t matured enough and they were above him on the pecking order. This changed once he got them under control.

He's a 'stranger'.
This is an integration problem.
Keep him separated by wire so he can heal and the girls can get used to him being around.

Here's some tips and links.
Integration Basics:
It's all about territory and resources(space/food/water).
Existing birds will almost always attack new ones to defend their resources.
Understanding chicken behaviors is essential to integrating new birds into your flock.

Confine new birds within sight but physically segregated from older/existing birds for several weeks, so they can see and get used to each other but not physically interact.

In adjacent runs, spread scratch grains along the dividing mesh, best if mesh is just big enough for birds to stick their head thru, so they get used to eating together.

The more space, the better. Birds will peck to establish dominance, the pecked bird needs space to get away. As long as there's no copious blood drawn and/or new bird is not trapped/pinned down and beaten unmercilessly, let them work it out. Every time you interfere or remove new birds, they'll have to start the pecking order thing all over again.

Multiple feed/water stations. Dominance issues are most often carried out over sustenance, more stations lessens the frequency of that issue.

Places for the new birds to hide 'out of line of sight'(but not a dead end trap) and/or up and away from any bully birds. Roosts, pallets or boards leaned up against walls or up on concrete blocks, old chairs tables, branches, logs, stumps out in the run can really help. Lots of diversion and places to 'hide' instead of bare wide open run.

This used to be a better search, new format has reduced it's efficacy, but still:

This is good place to start reading, BUT some info is outdated IMO:
