I am happy to report that I stuck it out, it took quite awhile, but it did work and I had all 4 eating out of my hand today. We sent the new white hen away for about a week, she wasn't accepted there either, they ended up keeping her in a cage there also. But were able to bring her back to a larger, more improved coop, where we had to also keep her in a cage also. We let them out loose in the yard with supervision for as long as we could and then we got to the point where we left her cage in the coop, but open. She felt safe there, but could get out and go to the nesting box, walk around and still be able to retreat to "her" cage. Slowly but surely she gained weight and they worked out their pecking order. She is at the bottom, but now she "belongs." Don't know if this will help anyone else, my partner was ready to give up and send her back, but she is our best layer and I for one am glad we stuck it out.
