Hen lost baby, can we replace?

[anarivers]

Hello,
I have a hen that hatched a chick in the last 24 hours. Sadly, the chick was unable to finish the hatching process and died. We took the egg/baby away but the hen is still sitting on the nest as if to be waiting for her baby to hatch. We happen to have chicks that we hatch via incubation. So my question is, can we slip these chicks under the hen at night? Will she treat them as her babies even though these chicks are weeks older than the one she would've had? The chicks are still "babies", just three or so weeks old.

You can put them under her but watch her reaction if she does not want them she would probably start to peak them

3 weeks is too old. You need day old-3 day old chicks for her to accept them.
