Reintegrating injured chicken

[Spunky1]

I recently let my single hen hatch some eggs to create a new small flock. I kept five and they are now nearly 4 months old. I was so pleased that they were forming a happy little flock without any squabbling or problems. Until... the little rooster injured himself on a piece of wire and the others were pecking at the wound. I separated him out into a small run with a hen that wasn't pecking him to keep him company. This run was close to the main one so they could all still see each other.

Yesterday I put the two back with the rest and things didn't go well! The mother hen was quite brutal to the rooster and also chased the little hen but to a lesser extent. I wasn't expecting this. They were only separated for just less than two weeks, and they're so young. It's barely any better today with the mother hen not letting either of the two near her or the others! It's breaking my heart to see a previously happy settled little flock split in two! Will they eventually reintegrate and become friends again?

Can the 2 chickens in the small coop and the rest of the flock still see each other? Start letting both flicks forage together for a couple of days and then put the 2 chickens into the henhouse one night. The next day there will be some small squabbles as they all find a place in the pecking order, but after that they’ll be fine.

It is normal behaviour to a large extent. More space and more than one food and water station will help and objects or baffles in the run that will allow the bullied birds to remain out of sight of the others .... but don't create any dead ends where they can get cornered. Broody hens often become quite antagonistic towards their offspring once they are old enough to fend for themselves. I assume you already have a rooster in the flock (since you hatched eggs) and it is normal for young males to be run out of the flock by the mature birds as they reach adolescence and live more on the perimeter, so I'm afraid it may be that your little flock will never be the happy unit you previously had.
