The rooster's motive

[eggsgalore]

I got a new rooster whi is a delight in many ways. Not aggressive to people and caring for the hens from the very start.
Except for the broody hen (she does not have eggs). Whenever she is off the nest he pecks on her. Here's my idea. I know he is an OK rooster, who was raised in a flock so I think the reason he does that is to force her off broodiness to ensure that no chicks hatch that aren't his. Like a lion taking over a pride and killing the cubs.
Any input from you guys?

I think he is either establishing a pecking order or she is his favorite and wants to mate with her. Just my opinion.

She is definitely not his favorite chicken since he already has one. And she is not fighting him at all.

He might just be worried that she has separated from the flock and is trying to get her to catch up.
