I'm hoping someone can give me some advice. I have a male duck who seems to be getting frisky with my female chickens. I lost my female duck in August and he intergrated with my chickens without any problems, until recently. I've noticed some blood on eggs and wings of my girls and have been keeping an eye on them, but no one seemed hurt. But I just caught him on top of one of the girls and she has blood on her head(I think from him grabbing her with his bill). I don't have any roosters, just the two girls and him, what do I do? He has been with them so long, he sleeps in the coop, and hangs with them all the time, even when they are free ranging. Will he hurt them, do I need to seperate them, or should I look for a home for him?
