4 day old chick opening & closing beak

[cc pine]

4 day old Brabanter chick opening and closing her beak almost constantly. Seems to be breathing through her mouth. She is active, drinking, eating (medicated chick starter), and pooping normally. No coughing or sneezing or mucus. Sleeping fine, but opens and closes beak while sleeping as well. (other 6 chicks are doing fine). Heat lamp temp is ~93° and chicks are spread out normally. We also looked into her throat to see if any food is stuck (all clear) and gently felt her throat and detected nothing abnormal.

I am not sure
does she pant or have labored breathing?
panting or labored breathing could be a sign of dehydration, heat stress, or exhaustion.
I actually had one of my chickens do something like your describing a year ago on a very hot day. But she was fully developed so I do not know if this compares.
Hope this helps

This happened to me thid year, my chick was breathing through her mouth because her nostrils hadn't fully formed. How do her nostrils look?

She may be too hot. That sounds a little like gasping. I would raise your brooder lamp or put a smaller watt bulb to make the tmo more like 90, with plenty of cooler area in the brooder.
