Depends on the mom. I had one hen that would adopt any chick/poult that came along while she was brooding.
But another hen lost her clutch and she tried then to kill any poult she saw.
If you want I would say give it a try just be watchful and see how she takes to them.
The poults would have to be a couple day old so the can imprint to the hen. Otherwise they would be afraid and run away from her. Also introduce them at nigh so in the morning when they pop out from under her, she will think that are hers. Good luck
