Chick with weird breathing

[GardenAndRoost]

I bought three splash maran chicks off someone locally and they’re all eating and drinking and active BUT one of the chicks has been open mouth breathing for about five days now but otherwise doesn’t seem sick at all. Is otherwise alert, any advice is welcome.

I moved this thread to our Raising Baby Chicks forum, I hope the little one will be ok!

What is the temp in your brooder on the floor beneath the heat source?
