I'M NOT SURE I CAN GIVE HER WATER THROUGH A DROPPER BECAUSE SHE JUST SPIT UP A LITTLE BIT OF WATER. SHE KEEPS HERE EYES CLOSED AND I OCCASIONALLY HEAR A SMALL CLICKING NOISE WHEN SHE BREATHES.
Sorry you are facing this..
It's failure to thrive... the clicking is because she aspirated fluid into her lungs which are now moist and she is struggling to breath causing exhaustion...
It does not sound like fluid will help your chick and is not likely caused by illness or disease that you should concern yourself with.
If she ever comes around to peck at food.. offer the chicks feed, crushed extra fine into a powder. It goes down easier and has increased my survival rate. I even do it for standard chicks now.
If you have or have access to Poultry nutri drench the way to administer to a chick with aspirating them (according to my experience) is hold it in your hand with beak facing the bend in your forefinger. Do a drip just below the nostrils and when the drop roll around into the beak the chick will instinctively gobble and swallow. Use the crook in the bend of your finger to help catch and direct the drip back to the beak. The nutri drench is a great supplement in times of need.. it has amino acids that other vitamin/electrolyte packet mixes usually do not. If these chicks have been shipped, that's extra hard on these tough little buggers.
Make sure they are kept warm but not hot.
Not sure if she's having issues with her crop also, possibly have not actually connected food yet even if it was pecking around like it.. Blockage called pasty butt is deadly fast.. but 3 days is early for to me, check it though and do so daily until your out of the woods.
In theory even if the crop isn't working the chick would still be getting some energy support from it's yolk reserve that last about 72 hours. Chicks sold at feed stores as day old are often 3 days old before arrival there.
I'm sorry, I've hatched hundreds of chicks.. prognosis is poor but not impossible. I have even caused the aspiration and subsequent loss myself dipping beaks and really hate doing it now. I think it can be also be caused by a wobbly chick trying to get a drink and dunking to far, or tripping, or being bumped by a brood mate.
I don't know of any way to get fluid off the lungs, but truly believe that is the primary issue with failure to thrive/connect as a possible secondary concern.
Wish I could be more help and encouraging.
