He looks pretty good. Glad not too much damage was done. Don't forget though, he's not really mad at you. Somewhat stressed and fearful, but not mad, and he's fulfilling his role as Flock Protector, Defender of Pullets. (Sounds more acceptable that way.

) Petting him may not be the best thing, as he could lose his fear/respect for you and act aggressively. Handle him as needed, but if he's leery, he is probably not going to be one of those teddy bear type roosters. Personally, I think most of the temperament is genetically determined, and I wouldn't want to push my luck.
Too bad about your dog. Both my dogs wanted to chase and pluck. Fortunately, I have enough room to fence off a dog-free chicken zone. Took about a year, but the dogs and I came to an understanding, and now they are trustworthy around all the chickens (even Seramas). Chasing instincts are now directed at squirrels and the neighbors' cats.
