We have 5 hens that are just over a year old. 4 RSL and one Dom. We also have 4 EE that are almost 9 wks old. Right now that little ones are in the old dog house with a make shift fenced run about 2 ft apart from the big girls 12 X12 run. They see each other, however I haven't seen them checking each other out as much as I thought they would. Maybe their not close enough.Anyways, what is the best way to integrating them? I am thinking of waiting until the little ones are a few more weeks older so they will be 11-12 weeks old. We don't and can't free range. One issue we may have is that the new girls don't use any roosts, they have one in their house but they sleep in the floor behind it at night. Any advice would be great! I want to this to go as smoothly as possible.
