I've got 3 baby chicks that are a week old today (our first chicks!) One chick has runny or very soft brown poop - it looks distinctly different than the nice little poop packages her sisters produce. All chicks are eating, drinking and sleeping well, they don't huddle under the light, and seem very comfortable. Am I being a mother hen to worry about the runny brown poop? (no signs of pasty butt btw) I doubt breed is an issue - but this chick is one of 2 Silver Wynadotte girls. Our other chick is a "Cinnamon Queen" Thanks!
