How long can they stay in incubator?

[KikiDeAnime]

I have to leave for work in 30 minutes and I won't be home until a little after 8pm. My dad will get home around 4:30 or 5pm.
We've had 3 hatch already and they're with some chicks in the brooder.
I thought the last 2 would be hatched out by tonight but they're pushing their way out quicker than I thought they would.
.
Will these hatchlings be fine until my dad gets home?

They should be fine.

In case I worded it weird. 2 of the 3 currently hatched came out sooner than I assumed.

Ducklings continue to live off of the absorbed yolk for 24-48 hours after hatch. They will be fine if they hatch soon and are left in the incubator until the evening.

I had two hatch Tuesday night (5/24 PM) and the third hatched early this morning before I got up (5/26 AM). I waited to take them all out until around 8am this morning and they are all doing great. Yours should be fine.
