Just an update. I was out of town for a few days so I wasn't really able to keep a close eye on them, but I've been back now, and observing the chickens. In the morning the rooster is still a little jumpy, I think he's trying to mate and the girls aren't having it. When one gets close to him, he'll kind of jump at them and try to grab them, but they run away before he's able to. He seems to calm down later in the day.
The two feeders definitely seem to be helping as far as everything else. The chickens are sort of able to escape each other and still eat. The girls aren't laying eggs yet but the days are getting longer so hopefully that isn't far off.
