Help! 3 day old chick not moving or chirping

[Beamgang]

She was fine yesterday. Today she isn’t moving. She was laying in the back of the nest. Momma and other two babies were eating.
What can I do to help her?

Thank you all for the help.

She passed away.

Sorry that no one answered and you lost the chick. Is the broody showing the others how to get to food and water? Are the rest of the eggs hatched? There probably was something wrong with the chick that made it weak. Sorry for your loss.
