these guys grew up together. and i recently removed my roosters hen, because im gonna breed her to her own kind. anyways, in one pen i have my rooster, and 2 ducks, 1 being a drake. so he has a mate. but when the hen WAS in there, the duck would get mad at my rooster for trying to mate with my hen. But even now i see the drake biting at my roosters wattles. whats going on? help me understand. heres the two... if the drake was bothering the rooster, wouldnt the rooster fight back?
