Right now I have two adult hens that are 3 years old. One is a RIR and the other is a Gold Star. I am working on integrating twelve 6 week old pullets. Right now I have the hens "downstairs" in the enclosed pen under the coop. I put up plastic on three sides so they have a wind block. The pullets are "upstairs" in the actual coop. Then I have the run divided in half with wire mesh so they can see each other. My adult hens are furious that they can't go upstairs- therefor they bully the pullets past the point of trying to find the pecking order if I let them have access to each other. My pullets are scared to death the leave the coop anymore because the hens fly at the run trying to attack them. This is becoming a huge problem and I don't know what to do! I can't divide the upstairs of the coop in half so they can spend more time together because there would not be enough room on one half for the 12 pullets. This is way more difficult than I thought it would be. Does anyone have any ideas?
