I think you are absolutely worrying prematurely. Usually when babies hatch they have lots of extra food reserve from the eggs. I would agree with others who say don't even try feeding before the shed. If you do, fine, but don't bother with all the extra things to encourage feeding <braining, scenting, tease feeding etc.>
Remember to not try more than every four days, and don't handle the little bugger at all until they have established feeding.
I have what I think is the world record this year for non feeders, and some have hatched in May. Only two out of seventy some odd, look like they are in any danger or kicking the bucket and they were born twins out of one egg.
Luckily after the two months all of the sudden some have started eating on their own with no extra encouragement. Even more have taken quite well to the tease feeding, so I have lots of hope!
Don't forget the method that works like a charm for so many, washing the pinks in Ivory soap!
Good luck, I'm sure you'll do fine!
