Yesterday while I was walking out to go give my ducks some treats I saw my Head male Drako mating with my younger male Wilson... Wilson along with his sister Oswald are new to the flock, and Wilson is taking a beating. He usually is on the opposite side of the fence as the others but still stays with them. There is not really much damage being done that you can see. My head male duck Just chases him all over the yard an mates with him too apparently... :/ is this just a ducks way of establishing a pecking order? Should I be concerned?
