I have 8 chicks. Four are 2 weeks today, four are 1 week today. I have seen an orangeish mustard somewhat runny poo in the brooder box. I've seen normal ones as well. Is this anything to be concerned about? It does look a little like this photo that someone posted earlier with the word Ceacal, I'm not sure what that means. But it looks this color and maybe even a tad runnier.
