He may leave them alone if he has enough ducks to satisfy him?He shouldn't hurt them at night then? Maybe I will let him just wander about...and he will come back at night to go to the coop? But, then again, maybe it would be better to pen him up. My chickens like to hop their run once in a while...
I probably could sell him, but my kids love "her." Wait til they get home from school and I tell them what I've found out.
