We have a male swedish blue that is an idiot to put it plainly!! He has attached to a particular hen of ours and will defend her to no end. We recently got a new full grown rooster that isn't starting any fights with him but since the duck won't leave him alone he's begun to retaliate and now the duck has a bloody nose...lots of crust and his nostrils looks ripped a little bit. The rooster is fine being around him and there is a divider to keep the duck away from him but he is persistent and sticks his ducky head thru the wire to keep messing with the rooster who then rips into his face! It's all up to the duck to keep the peace but he just won't quit!! How do I end this constant battle and will there ever be peace or will the duck learn the hard way and end up dead or infected til he's sick from all the wounds. I have since let the rooster free range and the duck and hens are in an enclosure but the dumb duck STILL sticks his head out and gets beat up!!!! What is wrong with him?!
