I need advice on how to introduce my 5 new Rhode Island hens that are about 9 weeks old now, to my current flock. I worried there will be some little spats but I don’t want any of my chickens severely injured or my ducks. Cause my female hen currently is kind of a little jerk to my female duck, may be because they’re all sexually mature now and hormones are high. So when and how do I introduce my baby reds to the flock.....
