I've got one 3wk old chick who is sick. She was MUCH worse, with very labored breathing and constant coughing, neck stretching and chirping with no voice, but I started them on Corid this past Saturday morning and she's much better, VERY active as well as eating & drinking fine, but still has a lingering "cough". Not even sure what's wrong with her, but can you please take a look and see if you're familiar with this behavior, and if you think the Corid will help? Not sure what else I can try... I posted a video a few days ago but it got very few replies even though it's had over 50 views. Hoping someone, anyone will be able to give me some advice I'm brand new to chickens so any assistance would be SO very appreciated! Thank you!!
