Broody Hen - High 80s/Low 90s

[KikiDeAnime]

This week is going to be in the high 80s/low 90s so I know that I need to make our broody hen drink water and eat when she needs to.
I candled the eggs after I woke up and saw progress. One has been underneath her since Friday and the other has been there since Saturday. I'm also getting 12 KC/Cayuga eggs for her this Thursday but it'll start cooling off a bit by then.

How long can I keep her off the nest to prevent our 2 duck eggs from overheating??

…. I’m not sure I understand. You’re afraid the eggs she’s sitting on will overheat? Are you talking about a chicken or a duck?
That’s not really a concern - her instinct should tell her when to get off, go eat and drink and come back. She knows when the eggs need to cool and for how long.
also, if she’s been sitting for a couple of days, adding new eggs is a very bad idea. You will end up with a staggered hatch… mom will want to care for the hatched chicks / ducklings and abandon any other eggs that are not ready yet to raise the new.
Not sure if I helped at all, forgive me if i completely misunderstood.

Broody hen is a Blue Wyandotte, the 2 eggs underneath her are from our own duck flock(KC & Indian Runner)
I'll be taking the 2 that hatch and selling them first before the others hatch. I will have a brooder for them.
And I've tried to let her be every since she first went broody but yesterday I found her nearly passed out from the heat. She could barely stand so I decided to start kicking her off the nest to prevent her from dying. She's very determined.

Is she in a well ventilated area? I have heard that sometimes people have to remove their hens from the nest to make them eat and drink.
But again, I wouldn’t add new eggs this Thursday. You don’t want a staggered hatch.

She is.
I understand I could end up with a staggered hatch but I already made plans with the lady I'm buying eggs from. Plus I may end up taking our 2 eggs out anyways once the new ones are delivered.
