Long story, but the short version is that I have 3 new hens (about 16wo) that I am trying to integrate into my flock of 9 1yo hens that were all raised together. They aren't killing "the newbies", but they chase them so much they all just hide all day. One is brave enough to come out a bit, but they usually stay in the coop. Sometimes I (or the bossiest hen) will kick them out, then they hide in the dog kennel I put in the run for them. I am afraid they won't be able to get enough to eat /drink this way. This has been going on for 4 days now. Is this okay? Will they eventually work out out? The "rest of the story" is below ! I had a happy flock of 9 hens, but picked up a new one at a swap. As recommended, I waited until everyone was roosting peacefully and tucked her in for the night. I went out early in the morning to see how things would go. She just stayed inside the coop! I think my perches were maybe a bit high for her, so I put her on the floor of the coop and let her come out on her own. Everything seemed good at first. A few pecks here and there as I expected - then all 9 hens piled on her. I shooed them away, but they wouldn't stop. (She is now living in a smaller coop I have with the three 1 month old pullets I also picked up.) I did the same with another and she is the braver newbie. I then got 2 more 16 wo pullets and tucked them in at night (one one day and one the next). I don't think they have ever left the coop voluntarily. I don't have food or water inside, but I added more sources outside - which are very attractive to the existing flock. The newbies go from roosting to hiding inside or under the coop, to being chased around the run. This can't be good! Please help!
