How long will she sit for after they hatch?

[_ADM_]

So my mix batch of 6 out of 11 eggs (4 silkie bantam eggs and 2 ISA cross) started hatching last night and hatched sometime today. 3 out of 6 have hatched, both ISA Xs and 1 silkie. I did a quick gentle candle of 2 out of 3 of the unhatched silkie eggs and both were still alive.
Just 2 questions:
1. I have a broody silkie bantam hatching them (not her first time) and was wondering how long will she sit on the remaining eggs till she leaves them.
2. The night while they were hatching I could hear the chicks that were hatching nocking around the other eggs. Will this effect the hatch for the eggs that still havent externaly pipped?

Im surprised that the silkie bantam eggs didnt hatch earlier but they are the late ones. The eggs are within a few days old of each other so they shouldnt be to affected by age.
Just worried that she will get off the eggs before they have time to hatch as they are still alive.
Thank you and will keep up to date.

I think my first time broody silkie sat on the chicks for about 3 days and when they all hatched I moved them out of the nest box.
I don't think the unhatched eggs would be affected by the chicks moving them around. I think I once heard that the hatched siblings walking over the eggs let's the unhatched chicks know that it's time to hatch or something. I might be wrong tho.

There is no guaranteed time. You don't get guarantees with living animals. I'll go through some information but this is theory. Real life doesn't always work this way.

Since the chicks absorb the yolk before hatch they don't have to eat or drink for over 72 hours. That's why they can be shipped in the mail. This is nature's way of letting the hen stay on the nest to hatch the latest eggs instead of having to leave immediately to find food and water for the first to hatch.

After internal pip but before the eggs external pip the chicks start talking to the broody. If you hatch in an incubator you can often hear these peeps. This lets the hen know they are coming. The first ones to hatch tell the hen when they are getting hungry and thirsty but this should not be in the first 72 hours. This is theory, some broody hens are better than others.

I once had a hen that hatched her first chick late Monday night. She did not bring her chicks off of the nest for 80 hours, early Friday morning. Those chicks were fine. I assume she had some late hatchers. I've also had hens that brought the chicks off of the nest in less than 24 hours of the first one hatching. Best I could tell there were no other eggs with living chicks in them. But I can't give you any guarantees.

2. The night while they were hatching I could hear the chicks that were hatching nocking around the other eggs. Will this effect the hatch for the eggs that still havent externaly pipped?

I seriously doubt it. Under a hen, the eggs aren't going to move nearly as much as they do in an incubator. I haven't seen any issues with that in my incubator, though again with living animals I don't give guarantees. Besides, under a hen what are you going to do about it anyway?

Im surprised that the silkie bantam eggs didnt hatch earlier but they are the late ones.

I've read that smaller eggs will hatch earlier than larger eggs. That has not been my experience. A few times I paid special attention to that in my incubator. The size of the egg did not matter.
