We have 5 "older" girls -- about 1 year old, and 3 "younger" ones, who are now about 5 months old. When we first got the newest ones we tried putting them all together at night---didn't work out so well, the older ones literally drove the younger ones up onto the roost and they wouldn't come down at all! So we built an addition to the coop (as suggested by several people on this site) and that is where the younger ones have been ever since. They can see each other and have seemed curious. So one day we opened the "door" between the two enclosures and at first it seemed ok, they all went into the others "spaces". But then the younger ones appeared to get scared and took to the roost (again) and they stayed there. We then made sure they were all in the "younger" coop and the same thing happened, the younger ones were frightened and got up on their roost. We felt somewhat guilty for subjecting them to no food or water so we put them all back where they originally started (2 coops). That's where they still are today. We'd like to get them integrated, any suggestions?? 1) do we let them be together and just leave them alone to deal with it? 2) do we let one of the older ones into the "young" coop and see what happens? 3) do we wait until they are on their respective roosts at night, open it up and see what happens in the morning? 4) do we wait for the younger ones to start laying (probably in about a month)? HELP!! We will appreciate any and all suggestions!!
