I have 5 chicks, all about a month old. They are having really runny feces. Is this a problem? If so, what's going on? Note: I accidentally bought the wrong kind of feed- it's made for adult hens. I will go back to normal chick feed in a few days but i wonder if this is the problem. It's purina brand chicken feed- i have also noticed that Purina dog chow acts like junk food with my dog. Please reply!
