HELP!!! Day 26 duck eggs do I need to intervene? PANIC OVER - PICS

[duckking]

This is day 28 now actually. I know....I just flipped out that they had pipped but were not zipping. My last batch pipped and zipped in about 12 hours. Three have hatched just fine all by themselves. Two are in the brooder and one is still in the incubator drying out. The last one has zipped out a line about an inch long and it's bill is free and he/she is breathing fine, but I can still see moist membrane around it. Humidity is at 75 and I am assuming he'll just pop out when he has fully absorbed and is ready. I am keeping my eye on him though....

This is #1 Hatched yesterday and the second photo is of the first two. Second hatched sometime after 2:00am this morning.

Thanks for the replies....I really appreciate the response...even if I am being a dork and freaking out for no reason.

A friend wants 20 for their pond, so I'm going to be incubating most of the summer (can only fit in 7 eggs at a time). I do have a mallard nesting, but 2 of my chickens keep going in there and messing up the nest when she leaves it to eat and drink, so not sure they will hatch after being rolled around all over the place. Might try a couple in the incubator with the next batch.
