It looks like he's doing really good. If he was older and the hens had a rooster before, specifically, recently, then this probably would be going a little smoother, but for the situation at hand, this is normal. Notice the wing down? He's trying to court them and the hens aren't buying it (yet). Keep trying and I think they'll settle in eventually. Just remember, for a chicken it takes up to two weeks for adjustment, so you will have to give them time. Personally though, I do think they'd adjust faster if they had access to each other all the time. I've noticed things take longer when they don't.
