Strange behavior for drake?

[un-named543]

My call drake free ranges with 6 other hens, one of which is his daughter from last year. I notice he is mean to her; chases her out of the pool and away from the feed, but not mean enough that they need to be separated.
He is in breeding season with the other females but ignores her in that way. Is this normal? Is is an instinctual thing? Is that even a word?????

Many times a drake will single out a particular hen or two and "Ban" them from his flock. This may stop after breeding season but not always
