One of the chicks I bought yesterday sounds like it's muscus-y for lack of a better term. It's walking normal and eating but I can hear and feel it wheeze, kinda of. I'm so worried! What should I do for it? This is my 5th bath if chicks, but I've never heard this. We have ducklings as well, could that be a problem? I'm trying to keep the brooder as dry as possible.
