I'm a new mom to 16 RIR chicks that are nearly 3 weeks old. I feed grit with a non medicated starter feed as recommmended by the hatchery. All are active and eating and drinking well, and growing too fast for me (lol). When I just checked on the wee ones, I saw a funny dropping, solid and normal looking with a spot of red (blood?) on it. After checking all bottoms I can't find the culprit, but all seem healthy and happy. Should I worry or just wait and see. Not much sleep for me tonight!
