Broody Hen has gotten of eggs on day 3 (5-12 eggs hatched)

I'm on day 3 of of my eggs hatch. On day 3 a my broody hen is no longer sitting on the 7 eggs, 5 of them have hatched out of 12 eggs.

when I was look at the eggs in the nest box I noticed that two of the eggs have piped.

I have a egg incubator, should I out them in it ?

 

ok will do

 

They are now in the egg incubator. My mum and brother both think that the egg incubator needs to be at 39% temp and to also have a sleeping bag over the egg incubator to keep it warm.

I've read that it needs 35.5% temp for hatching, but my mom insisted that it has to be 39% temp, as the neighbor told her that it needs to be at 39% temp for hatching.

 

No all of the 12 eggs where bought from the same seller on Ebay and where all placed in the nest after 24 hours had passed. Also none of my other hens can get in the nest box, as I moved them to another chicken house, because they all like that one nest box for their eggs and the broody hen did like them try to get in the nest box.

I'll wait a 3 day or more and see what happens.

I've candled them, 3 of them look fully developed, I can hear peeping from many two of them and 1 look like its got nothing in the egg. no egg has piped yet.

 

There some pics of the chicks and hen.

 

Also I took a video of them too.
