I have 13 chicks I got 1 1/2 days ago. They are 1 week old ( acouple are only 3 days old). One or more of the week old ones has runny poop (orangish-brownish color) I got some chick feed from where I got the chicks and dont know if it has coccidiostat in it. But it is fresh. I will be getting medicated feed tommorrow. will this be enough? These are the chicks that had crusty butt and still 3 have protruding butts (still working on that)--maybe it was the medicine I put on their butt?
