I going to add atleast 4 hens to my flock this year. I have 6 now. 2 Brahmas (one is a rooster) 2 RIR, and 2 Gold Comet. Most of them docile. I've been home for 3 weeks after surgery letting them free range most of the day and have noticed them getting alittle more aggressive, mainly the rooster. Nothing crazy, for the most part they really are docile. He does get upset when I touch the hens. The flock is a year old. Any suggestions when introducing them in about 6-7 months?
