Your birds FIRST needs to be warmed up before she will be able to take in water to rehydrate (and also for shock) much less feed (Bird Rescue orgs always stress NEVER attempt to rehydrate or feed a bird with hypothermia! FIRST get her warmed up THEN rehydrate THEN feed). You can put her in a cardboard box to protect from draft which is very important (the cardboard is very insulating too)....if you have a hot water bottle put that under the shavings (or a sock filled with rice and warmed up in the microwave) ...
to recover from the shock ...
Once she has perked up and you are seeing her drink then you can think about feeding her... this should nOT be dry feed...make it moist with some cooked oatmeal and serve it warm (not hot)... you can also give her four drops of POLYVISOL (liquid childrens vitamins) into her beak once a day for a week. If whe begins to show any further symptoms then post those but at this time when she is in shock and hypothermic the above needs to be done first. please do not give her anymore sugarwater... in many instances it can actually exacerbate dehydration.
ETA: here is the main portion of that post re REHYDRATION and ELECTROLYTES (and I wish to stress that the electrolytes must be given
One thing I can say though is that I think your bird is dehydrated. I am glad you have moved the bird to a warmer place as this will ease its burden by not having to use resources to keep warm. Please note that ill birds (particularly with respiratory distress) should have a humidity of at LEAST 70%... protect from DRAFT...
With panting/gasping, birds have a physiological responce of acidosis and NEED electrolytes (it should also be at a lukewarm temperature) until you get the dehydration sorted out your bird will remain unable to properly process nutrition (and meds)... a "bit of salt and sugar"is insufficient IMHO here so you need a proper electrolyte really and I suggest you get a commercial brand (look at your feed sotre for DURVET > dosage:

If you have the 4 oz. packet of Vitamins and Electrolytes then you would mix ½ teaspoon into 1 gallon of water.
If you have the 8 oz. packet of Vitamins and Electrolytes then you would mix ¾ teaspoon into 1 gallon of water "
If you absolutely cannot find a proper commercial electrolyte (and remember you also have the option of subcutaneous admin of RINGERS solution if you can get that from a vet or other source) then here is an emergency "recipe" to make yourself but you MUST not delete or substitute any of the ingredients (for instance substitute glucose/cornsyrup with table sugar) here it is:
From "Practical Wildlife Care" by Les Stocker:
It is possible to mix your own equivalent oral rehydrating salts by using the following ingredients:
7g sodium chloride (NaCl, common salt)
5g sodium bicarbonate (baking soda)
3g potassium chloride (commonly called "Muriate of Potash". Salt substitutes contain mostly potassium chloride)
40g glucose (a common source is corn syrup)
2 litres water
The solution must be mixed thoroughly and discarded after 24 hours..."
Rehydrating your bird is the first step to getting her better... after rehydration and some nutrition (we discussed the handfeeding formula
)
