I'm incubating eggs, Q: Will a broody hen adopt the chicks once they hatch?

[Scorpy89]

So as stated, I'm incubating eggs in a bator.
I have a broody hen that wants to sit and hatch, but she keeps cracking the eggs she sits on ( mostly likely from guarding.) I only noticed that they were cracked once she abandoned them and tried to sit on a new clutch of eggs (I candled them.) They are hairline fractures, but somehow momma hens just know when something is wrong about eggs.
So the Question: Will that hen be likely to adopt the chicks that hatch?
The reason for the asking is for her health, I don't want her stressing herself out in the coop while it's hot outside. I live in a hot and humid area, the temp can easily reach 100 at times and the humidity can reach 70 or more at times, it is especially bad after rainfall. So if I can curb her to just raise chicks I will. Otherwise I'll have to continue to try to break her of being broody.

Well it realy depends on the hen. (I've had experienced all) some will peck the chicks and some will take them in, And some hens peck the chicks to go under her so there warm and not in a harmful way. Just try and keep an eye on them so make sure the mama takes them in.

so about 50/50 then? She's only a about a year old, and started going broody back in July, she's started seriously trying at the beginning of the month. She's a New Hampshire Red Hen if that helps. Oh, would it help to move her and the chicks to a coop near her current flock mates so that her flock mates won't get attacked but they can all still she each other? I hear that's something people do.

If your hen wont sit on a clutch and moves to another once some eggs have broken how likely is it she will still be sitting and broody when the eggs in the incubator hatch?
That's the first issue.
Assuming she does sit for the full 21 days the incubated eggs need to have hatched close to the end of those 21 days, so timing is important.
Why are the eggs breaking? Perhaps if you could solve this problem it might help with the sitting.

 

[Folly's place]

If she's with her flockmates, so they can get into her nest, it's a often a problem. It's best for her to be in the coop but separated from the other birds, so she has her nest all to herself. That might mean closing her off somehow, with space for her food and water, or moving her with her eggs into a big dog crate at night with a small flashlight for minimal disturbance.
If the egg shells are too thin, fix that problem; it's likely diet related, or can be genetic if it's only one bird's eggs.
Some broodies will accept chicks, others won't.
Good luck!
