How long does hatching last?

[FussyHen]

One duckling hatched this morning, none since. How long does it usually take for all of the eggs to hatch that are going to? When should I remove the non-hatchers?

That depends on whether they were all started at the same time, and you can have a spread between them even then, sometimes as much as 2-3 days. Are you incubating these or is a duck setting on them? Have you candled them recently to verify that they're fertile and that the babies are still alive?

I have 3 hens and a drake. I don't know which the eggs came from, possibly all three. The hen was setting before I realized it (they're free range days).

She kicked two eggs from the nest and I candled them: both dark on one half (lengthwise) and light on the other, which means nothing to me. This happened a few days ago.

Trying to find info online, they warned about dangers of turning or handling near the end, so I didn't.

It looks like still the one duckling this morning.

The two that are half dark are probably embryos that didn't make it. Is one of the ducks still on the nest? If so, I'd get the eggs when she goes for her swim and do a quick candle to see if any of the babies are still alive.
