I have 12 RIR chicks that are a week old. Two of them have been having a foamy looking poo. Now it looks like some might have some blood in their poo. The poo spots after they dry have a dark red ring around them and some of the poo is dk. brown in color and runny. That is why I am thinking blood. Would it be a bad thing to feed the chicks a medicated starter food and give them an antibiotic in the water at the same time? I don't want to make any problems worse by over medicating! Thank you! Here's a little bit more info. All of the poo from the chicks is not foamy or runny. Only some. Am I just worrying about nothing? They are so cute and sweet I don't want anything to go wrong.
