Has anyone experienced this..chicken appears normal, but poo is loose (not watery) and is only a dark rust color. However, does not appear to be bloody. Chickens are 6 wks old living under same conditions. Now another hen has same type of poop. Some are dime size or as big as quarter size. Should I be concerned? Thanks I did see the "poop Link", the pix was blurry but appeared to be rust color and mentioned cocci.
