So my lovely little rescue hen, Lucille, has been integrating well into the flock. But in the last week the bedtime routine seems to have changed. We have two coops inside a larger enclosure for safety. My existing flock was all sleeping together in one coop, with Lucille as the odd man out. Eventually I decided to just move her in at night, while everyone was sleeping. That was awesome! Within 2 nights of that, she seemed to have much improved her status in the flock, and seems much more friendly with Fiona, the Coop Queen. Yay for Lucille!!! But now my two oldest hens have left the group and they're sleeping separately in the other coop. I don't know why! I even built a new, longer roosting bar over the weekend to make sure that all the girls could fit comfortably! Ugh! I really want everyone to get along. So the last 2 nights, I have moved my older hens, Olga & Annie, back in with the others, so everyone would be together. Oh, Olga gets so angry with me about this! Should I keep encouraging them to sleep together? (I could close up one coop before bedtime.) Or just let it go? What difference does it make? Will sleeping together encourage a more unified flock?
