My healthy, active four week old chicks still have runny, butterscotch colored poop, altho there is also plenty of the solid "earthworm" looking stuff in the brooder also. Is that anything to worry about? Just asking because they also sneeze once in a while and one is growing a little less than the others, but she is perky and active as the others. If they were my kids I wouldn't even blink, just tell them to eat a banana! But with these chicks it's all new to me!
