luckyfan101,
don't worry sometimes eggs will hatch a day late with no issues. 2 of my 11 ancona duck eggs hatched early at day 25 yesterday and they seem to be pretty normal, slightly weaker than ducklings hatching at the right time but its pretty clear that they'll make it. if your eggs are still moving they seem fine, just give them another day. By day 30 noipped you may want to poke a hole in the air cell side of the egg and make sure they are not shrink wrapped and cant get out. A couple weeks ago I had some chicks who still hadn't hatched on day 24 I poked a hole in the egg to see if they were alive and they were completely shrink wrapped. It was so sad I saw their little faces and beaks through the membrane! I felt so bad that I had waited too long.
chook27,
maybe once it gets more rest try giving it a warm wash under the faucet with some gentle shampoo? it could have some goey stuff stuck to it preventing it from fluffing out. In my experience chicks fluff out in a couple hours.
