Someone suggested it could be cocci. From what I've read online it chick should be sicker than he is? Just trying to clarify - I have some Corid in the mail just in case. Whichever one it is has had it off and on for at least a week. They're two weeks old. From what I can tell it's only one or two chicks out of the seven. No signs of listlessness, feathers are all healthy and they're all active. They have a heating pad for warmth. Food/water gets changed daily. When I moved them to my garage I did find a small water spill in their cardboard box I had somehow missed. I'm not sure how long it had been there, though. For the most part I've kept up on keeping their cage clean. Temp has been steady. The chicks seem warm enough, so if it is temp it would only be one or two that are cold. The poo is VERY stinky, and almost a liquid sometimes. I'm still locating which chick it is. It's for sure not all of them. Cocci is the most common ailment, but where it's been going on so long should I check for something else as well? Could the one chick be somehow cold when the others are warm? Whoever it is stank up my entire garage last night when they pooed on the heating pad. Any suggestions for better ways to track down who it is? They're all very active and love jumping, so isolating them has been a nightmare. I should also add that they're on medicated chick feed. It was the only one my local store had in stock at the time. I give them some clean yard dirt for grit. They also roam my back yard a lot these days.
