sulking chicken

Not been here for ages. Lost one of my old girls last year which left us with one chicken.
After being on her own for so long decided to get a couple pof new girls. I put these in the coop for the rest of the day and in the evening put the old girl with them, a little argument but nothing serious.
Yesterday and today the old girl has the stood up the end of the pen sulking like a big kid.
One of the newbies is eating wel and strutting about like its been here for ever.  The other one is eating and preening but seems subdued, likes to stand in corner and just have a little walk. Is this just from being transported to new home? They are point of lays but this one is the youngest.  She also has one eye closed so wonder if old girl has had a little go at being a bully.  Just got fingers crossed she will be ok.

Little update, Girls now getting on and no sulking.
The smallest stills seems a little off colour but can't be too bad as she jumped up onto the top of the housing yesterday, will have to watch her or i will find her in the field. Just waiting for first eggs in a couple of weeks
