My chickie book tells me that every tenth poo comes from the ceca, an area of the intestine. So some poos will be runny. Knowing that, I didn't freak out when some of my babies' poos were runny. I'm soooo glad they're doing well! They probably need only medicated chick starter and clean water now! Yea! Do you have any aviacharge 2000? It's a wonderful water supplement that gives a nutrition burst to your sweeties! They are adorable! Congratulations on your new babies!!!!!!!
