So I'm trying to get three older D'anver hens to accept a young D'anver rooster. The older hens where with a rooster before but he died from being sick. So I'm trying to replace the rooster but the hens ain't having it by fighting him. I have a mixed flock who free ranges so I'm familiar with integrating other chickens in and tactics to make it work. But for some reason these hens are just so stubborn and have ever since push my large fowl eggs layers around. I'm open to any suggestions, I'm struggling with this one.
