Why do chicks breathe heavily & open and close their mouths?

my 2.5 week old polish chick is opening and closing its mouth.

Is this a good medicine regime?
Tylan-oral
Multivitamin
Paracetamol

Or

Amoxicillin or any other antibiotic?

I’m really worried.

Is it too hot?
I wouldn't use an antibiotic without knowing the problem is bacterial. Prophylactic use is how antibiotic resistant superbugs are made.

My guess is too hot. Can the chick get away from the heat source? Is the brooder large? Is is a rubbermade tote (or similar)? I hear those can just get hot, overall, especially if on the smaller side a with heat source too close/too big.

Make sure there is water and that chick is drinking.
