That's a funny and sweet picture. Is Ursula still separate from the main flock? Does she have a place to roost at night? If not (and I'm just guessing here) she may be more reluctant to let them go as they are her flock now. Anyway, I agree, I think she will be fine after they are taken away, and will happy to rejoin the flock again.
As a side note, when my ultra dedicated broody raised slow broilers, she had mostly weaned them by butcher date. But, I did leave her with a couple of the smaller pullets to "console" her although it was probably completely unnecessary. I ended up not butchering the smallest of those pullets and she went on live for several years. She was great layer and sweet hen. I still have a few of her children and grandchildren in my flock.
