New pullet being badly bullied

Hello All - one week ago we got two new chickens (about one year old)from a friend who could no longer keep them. One unfortunately died the next day - assume from stress but underlying weakness. Then this weekend we got a 16 week old pullet on basis that hens are social creatures.

Unfortunately the original chicken has really not taken well to the newcomer. She relentlessly attacks her. We have made them sleep in the coop (an Eglu) together but in the day she attacked the little one so much that we took pity and let them both free range. They spent the day at opposite ends of the garden, with the new one running to us for cover every time the original hen made any advances towards her.

We can't put wire down the run because only one would have no access to the house incase it rains. We have instead converted our summerhouse into a temporary henhouse, splitting it in the middle with waist high wire. Otherwise we have pulled out the door panels and replaced them with chickenwire and the windows are all glass but we have covered the lowest part of them with newspaper.

Does anyone have any inkling as to how this arrangement will work for our hens? Is it likely to stop the bullying? What would be the best way of dealing with them? Could the original chicken actually kill the new one- what about in an Eglu?

I have had chickens in the past but never just two and have never seen a new chicken bullied quite so intensely.

Any responses gratefully received.

Just turn a blind eye, and let them sort it out, the way chickens do. at the end of the day the older hen is just protecting its territory, the new hen is an intruder who needs to be put in its place, the older hen will probably attack the younger one for a few days but after that it should all settle down with the older hen being the dominant one.

I just thought I would let everyone know how this was sorted out. Our chickens spent one week in the summerhouse that we had split down the middle with chickenwire. The older hen hated being in there but the little one I think was just relieved that she wasn't being attacked. After one week - or in fact 5 days - we put them both in the Eglu together and miraculously the bullying stopped!!! THe pecking continued a little bit but not in a serious way and now (a couple of weeks later) the two are the best of friends, which is a great relief to all concerned!!

Thank you to everyone who gave helpful advice and encouragement - much appreciated.
