If they still have unhatched eggs after 3 days of the others hatching they most likely won't hatch. And the hen will sit the nest until the unhatchable eggs are taken from her.

How many hens do you have sitting?

Guinea keets are a bit fragile for hens to be fighing over. I'd divide the hatchlings and seperate the hens and take them off the nest. Three days of hatching is getting close to time they need to eat and drink...

They may be sticking to the nest in defense of loosing their family to another hen who wants them all. Give them all a safe, seperate place to raise them and they'll get on with growing their family.....
