I don't know, I draw a fine line with roosters. I've never had one chase hens away from their food. My last rooster, even when he was young, dumb and inexperienced, always treated his hens very well. When I got 8 new youngsters and integrated them at 12 weeks old he took them right under his wing. He didn't try to mate with them yet and he certainly didn't chase them off of food just because they were new, young and not laying yet. So I guess if it were my bird...I'd be watching him closely and if he doesn't let up or if he gets worse I'd pull him out for a while and let the young hens have a break from the stress for a bit.
