how long after external pip does the chick hatch

[Finge]

welp, good news, the second chick to hatch is doing good, it has roommates of the sorts, my almost 7 week old pullets and my cockerel. I have a setup to where I have a brooder coop with it's own run that sits in my chicken's run. There is a door to the coop that I closed, since it's broken, so the older chicks hang out in the run while my little surviving chick is in the coop, so it has company, but they can't get to the chick incase they get territorial or decide to trample the thing.

Another question, is when I should give up on the remaining 8 eggs? they are currently 4 days late, but then again, the surviving chick, I've named chance, was 3 days late, and the weak chick 1 day late.

I would wait a few more days unless they truly look dead. In dead eggs you tend not to see any blood vessel or they will look brown and soggy. The chick will not be moving and liquid my slosh around in it. I know that sounds gross, but that's how I determine if I should give them a chance. Some eggs may have been set a little later or kept in a cooler corner of the incubator and so take longer.

Also if you gently tap on the egg and listen carefully you may hear the chick or feel it move inside the shell.

The second hatched chick died today, had breathing problems, was fine in the morning...

@Cntry1958 I did that with all the eggs after the first hatch, didn't nt hear anything.. though ill check again and see. The temps might have killed them in the end, which would explain why the two chicks didn't make it to day 2... it got to 115 during a day when the power went off and I cealed them in my room.

I am so sorry to hear you may have lost them all.

I know this is an old post but just thought my experience would help someone somewhere I am new to hatching and i stared off with 6 eggs. I have had 3 hatch easily but I had to assist the 4th. She pipped externally early hours of Saturday morning, around 3am. I expected her to hatch during Saturday time, no luck, the opening only opened slightly. Other eggs that had externally pipped after her were zipping. Come Sunday, I held my patiencce. The incubator had never been opened and humidity always between 65 and 75%. Monday unfortunately I was out all day and I had hopes that she would be out. But when I got back in at 8pm, egg was still the same. I decided to help, but at this point I didnt even know if she was dead or alive. It had been more than 48 hours since her external pip...So I turned on the shower to raise humidity. I then went to quickly snatch the egg from the incubator, wrapped in wet but warm kitchen roll. To my delight, I could hear her chirping from within the egg. But boy without help she wouldn't have come out. The membrane had hardened and it was good that i was in the shower room for this part. The humid air just helped soften things, I slowly peeled off the egg shell, leaving just the york bit still attached. The membrane just came off easily after, she was ready to come out! I quickly rushed her back to the bator and she looked exhausted, wasnt moving and i didnt think she would make it. But anyway, I had done what I can so I decided to let nature do its thing. I am glad to say that after a couple of hours she was banging about the bator, chirping away! So all in all I have hatched 4 out of 6 so far.
Egg no 5 looks infertile, egg no 6 am not sure if it will hatch, looks developed so will give it up to day 25 and toss.
I used one of those automatic egg turning yellow chinese bators because my budget wouldnt stretch to brinsea. However, i dont recommend them because the humidity alarm keeps beeping once humidity is 45% and below. I have looked for solutions online with no success. So that's my newbie hatch story.
