I have a nice BCM Roo that I want to put over my EE, for a Olive Egger. He is not the dominate Roo. My RIR gets all the respect and the action , I would like to separate but I dont want to mess up the way my flock all gets along . I have 17 1-1 1/2 olds . 1 BCM Roo , 1 RIR Roo , 1 Bantam Old English Roo that thinks he is Boss , 1 Guinea Hen , and 13 miss Hens , They all stay in the large coop that has lots of room and a 15 ft x 25 ft run. I also have 15 more chickens that are about 10 weeks , 6 roo's and 9 hens they stay in the small coop , that coop has a 15x8 run , that opens up to a large run thats about 30 ft x 40 ft . The large run is open to both flocks and they both use it at the same time. So they dont really hang out together its like 2 different flocks the little ones dont go to close to the bigger chickens unless they are really thirsty , they just stay to themselves. I would like to move the younger ones in with the main flock , and pull out the BCM and the EE and put them in the small coop and small run to mate . What would you do and how would you do it . They all get along in there own separate groops , what will happen when I try to make these changes? any help would be awesome .
