The doe is mounting the buck for dominance... not because she wants "more". I usually seethe rednessgone in a day or so, but it can take a couple of days for the redness to subside after breeding... especially if he "over did it".
The small "scabs" could be just be from being mated. He may not have been a total gentleman with her... but if you don't oversee the breeding you can't know that. I really never leave the rabbits to breed without watching. I'm not being nosey or perverted... I just want to make sure no one gets hurt, bitten orattacked. My vet had to put down a doe that was left to be bred and in all the running around, she broke her back.(Not one of mine!)I do have does that, as soon as they are bred,attack the buck and I have to get them out of there fast. Why take a chance?
If it takes them a while, do chores around the cages, clean, feed, whatever... just keep an eye on them.
