Here's an optimistic update: Lovey went up to the coop a little bit ago and I put the chick up and closed them in. She found the freshly hatched chick and took it right away, she was sounding very pleased. I made sure she was on the other one and she was eating some of the shell but then tucked it up under her.
Hopefully the age gap isn't too much of a problem.
