I have a 5 months old roo who's been mounting our girls for a month now. Then yesterday he chased down our female duck and jumped her! At first I thought he was attacking her like our other roo did. BUT when I get to them he is going at it!
WHAT IS HE DOING???
Is this normal for roosters? Our other rooster killed our male drake so she was left by herself. We now have like a dozen ducks but she is the only one that gets mounted, attacked, or whatever they're doing?
