I have a pullet I suspect has coccidia. She is 15 weeks old all huddled up and lethargic. She is getting thin. She is on day 2 of Corid. How long will the Corid take to work before I start looking into something else? No blood in her stool. She has diarrhea in the morning but it thickens during the day. She is rapidly loosing weight. I wormed her as well. She eats some, but not eagerly. She is drinking okay. She chirps and preens herself but you can tell she is off. She is thinner and thinner by the day. I dont want to cull her until I give her a shot. She has no respiratory sounds, but you can hear a gurgling in her belly. Thanks!
