Hello- I have a 2 week old chick, bought from a box store. It's been fine with no issue until the other day. Symptoms- sneezing, wheezing and gasping. And here's the mystery part, it's not all the time. It's random. No triggers like new bedding or food. She is in a hospital tank now. She will be fine for a day, then bam. Gasping, wheezing and looks like she's at deaths door. Give her about an hour and she's fine again. I have searched Google and can't figure out what's going on. Anyone have any ideas? Note- through all of this she is eating and drinking fine. The only things I have given her to aid through this is Poly-Vi-Sol, Vet RX on nostrils and roof of mouth, Nutri Drench and probiotics in the water.
