Due to a loss I only have 4 hens left of my original flock, two 3 year old barred rocks and two 1 year old Amberlinks. Yesterday I bought 7 Buffs, 4 barred rocks and 1 RIR. All hatched March and April of this year. I have them in a temp coop for quarantine, I am just curious when I add 12 new hens to the coop where the 4 have been living in what to expect? Last year I added 5 Amberlinks to a flock of 7 and things went pretty smooth. The first night a few of them were pushed out and slept in the pop door opening but after a day or so they got along nicely.
