one of my australorps (3 weeks old) had a very clear and runny poo. if I hadn't seen her do it I might have thought it was just some spilled water or something. She is eating and drinking fine and vent is clear. she has seemed a little more reserved the last few days, but I am thinking that is because another chick (pretty sure it's a roo) has kind of taken over the top dog spot. is a poop like the one she had a symptom of something?
