Cute chicks, I hope I did not give you bad advise on helping them out but in my experience after 24 hours with no progress they do not make it. Yours do seem plenty wet so I am not thinking it was stuck due to drying out. It is a gut call when and if you can help. You should always make sure they are full term before helping, I just assumed that they were when I suggested to help it out.
I used to have an incubation trouble shooting link but I can't find it so I am not sure why they were so wet, I know that incubator hatched chicks don't get fluffy as fast as one that the hen hatches. Her contact fluffs the feathers for them. I hope your little guys make it, they seem ok in the second picutre.
Chicks that have trouble breaking out often do not stand up in an hour. It is an individual thing. I have had some just flop around for several hours. As long as they do make an attempt to move and stand they just keep getting stronger and stronger.
The hard part is over, the first hatch is tough because one has no idea what to expect.
