3 day old chicks with clear poop

[Babybockbock]

I have 3 brabanter chicks who made it out of 12 eggs..it was a rough hatch and I lost one chick the day after.

All 3 are eating and drinking, and seem perky but at least two have clear poop with brown bits in it.

I have been cleaning them due to pasty butt as needed but I want to know if this clear poo is normal.

I have probiotics and electrolytes in their water ( not sure if this maters)

Not on medicated feed.
Id say the poo is 80% clear 20% brown.
I didnt think to get a pic when we had them out but I will be cleaning the brooder tonight and see If I can.

Thank you

Edit I was wrong they are 6 days old
