My 5 day old chick is gasping for air (not panting) and peeping loudly like it's in pain. Right now I have it cupped under my chin b/c it seems to calm it down and quiet it's frantic peeping. All the other chicks are fine. Is it too late for antibiotics to work on this little one? Is there anything I can do to make it more comfortable? I have a feeling it's not going to make it, but I hate watching it suffer.
