I have 3 hens I have had since March and 6 pullets I have had since beginning of September. The first of November I am going to move the 3 to a coop that has electricity. The 6 have been in that coop since I got them. My question is which group is new to the flock? I am assuming it is the 6. But the 3 will be new to the coop. How would I handle this?
