If you are in the mood to try something fun, this is what I did when I had one survivor left from one group that I didn't want to integrate into another: I let her become a mom!
I let her go broody by replacing the egg she laid each day with a wooden egg. When she was in a good and broody mood, I replaced the wooden eggs with fertilized eggs. 21 days later she hatched out the whole clutch! She didn't mind being by herself while she was sitting on the nest, as hens prefer to be alone then anyway. Once the babies arrived, she had plenty to keep her busy.
