So I have introduced some new hens into my flock, did everything that I could to make it run as smoothly as possible. Took the new girls and had them separated from my other two doing the whole look but don't touch for just over two weeks. I gave them time to free range together and was starting to get some pecking but nothing more than normal. So after a week of doing that I thought it safe to add them to the coop, I knew it was going to be hard so I followed the advice that was here of adding them at night, making a change to the coop so I added some more perches to the outside run, and even adding in a game for them where they have to jump up and peck at a bottle to get some chicken scratch to come out. Well it has been over a month and the older hens are still going after the new hens, it is too the point that they will not let them into the coop at night, they are being chased away from the food and water even when I am putting multiple out, the only time my younger hens catch a break is when I open the door to let them free range for a bit, the older hens will go out and let the younger girls down from their hiding places before they will come back and chase them out of the coop just to chase them back in. At first I thought that this was normal but with this going on for almost a month I am getting worried. Any advice?
