Green Poo in Newborn Chicks?

[thebeanboi]

Hey!
I just got 3 little female (sexed) Dominique Bantam babies, and they are so cute!

*cough*

Sorry not the topic we're on.

Anyways, I noticed in their box and in their brooder there was little green poo in the box and brooder. What is it?

It isn't dire, they seem to be behaving normally, curious, eating well, drinking well (when we got them in the brooder, I think they drank water for 5 straight minutes. Could it be dehydration?).

They were born on Wednesday, May 16, 2018 at 5:00 AM.

Thank you for your help!

First poos. It’ll change to a Brown once they start consuming more food.

Could also be the change in brands of feed..I'm sure they are fine.
