My chicks are producing a rattling sound at Day 6

[Munyah]

My chicks are making a rattling sound deep from the stomach area but they are eating fine and drinking fine. Kindly assist how best I can tackle that and how bad can the situation be.
Thank you.

What are they eating, any treats? Do they have access to grit?
A recording of the sound may help us to identify the cause. (You'd need to record it, then upload to youtube or something similar, and then link it here)

You may be hearing normal bowel sounds, just like humans with gurgling or growling sounds from the belly. Are the chicks active, eating and drinking, and pooping?

This is what I thought too, I remember hearing my girls tummies sounding rattly and crackly, it was just grit and food being digested
