I have three hens and two coops. My top hen has been alone in her coop after the loss of her sibling. I added two adult Cochins (full size ) and have integrated them during the day but not at night. It is time to move my alpha hen to the new coop, but she is not going to like it. I have let her explore it during the day. Do I just pick a day and put her in at night. I am a little nervous about how she will treat the other two in a smaller space. The indoor area in the new coop is small 4 x 8. There is a lot of vertical space, but the Cochins do not fly at all. They won't even roost on the perch that is 6 inchesIs of the floor. My alpha hen is a BR and will eventually love the high roosting options. Is there anything I can do to make this initial adjustment easier?
