Old hen doesn't like new house

We have a chicken (she looks like a brown leghorn, only she has a muff and beard as well) who is about 3 or 4 years old. She crows, acts like a rooster, and lays eggs. Anyway she had been missing since Saturday, a few days after several of my six week old pullets were killed.

She showed back up today and I locked her in the run/coop enclosure so that I would know where she was and would not have to worry so much about predators anymore (we have gone back over our coop with hardware cloth and new walls & doors). She has been free-ranging pretty much her entire life and is not taking well to being locked up.

The run is 272 sq. feet and she is currently the only one outside. She is throwing herself against the flight netting trying to get out to go roost in a tree and I am really afraid she is going to injure herself. When it has been dark a little longer my husband and I are going to go out and move her into the coop and lock it up tight. However how do we keep her from hurting herself tomorrow? I really don't want to free-range her right now... something has taken up in her usual roosting spot and she has been hiding in the woods for six days. We have possums, cats, bobcats, raccoons and several rabid animals have been spotted in the neighboring county. What do we do? I've tried feeding her a treat earlier but she was too upset to eat it and pecked at it and tossed aside. I really don't want her to hurt herself, but being a free-ranger right now doesn't seem plausible either.

 

We are in Banks too.

As far ast the nests, most of the nests we have been finding in the past two months have already been raided by the wild animals in the woods. The last one my husband found all the eggs were smashed and the insides eaten out of them, most of the others have been just plain empty. The nearest roo she would have access to is almost three miles down the road through lots of woods and many many dogs, so I know none of her eggs are fertile... I doubt she knows that though. We were willing to go without the eggs to give her the freedom, but when she didn't show up for six days I was sick thinking that she had been killed by something and I had been too weak on the subject of moving her into the coop/run.

We do have an 8 week old cockerel & pullet and we were planning on putting them in the run & coop tomorrow; how wise is this now with a really ticked off hen? My dad and husband seem to think that they will be okay and we should just watch her with them for a hour or so.

Also how are we supposed to get her calmed down. She sounded like we were trying to kill her when we grabbed her earlier and put her in the coop. (She had been roosting on top of it and started running around into stuff when we went to get her). This is all besides the earlier flightiness.
