I have a chick that I think is infected with it. She sleeps a lot eats a little has watery poop. Doesn't move too much. What do I need to buy to make her better? Do I need stuff for water and food? Do I need to treat the chicks in the cage with her? Help me out here guys! She is a bantam about a week old. Not on medicated feed (Should she be on it?) I am new to all of this. She doesn't have bloody poop but from what I here it isn't always bloody. But she is showing signs. What is the best way to treat it? Where can I buy the stuff to treat it?
