Hatching marans- eggs are chirping, no pips.

[Minky]

I normally wouldn't bother the eggs... but I have had chicks (17 easter eggers) hatching for 30 hours now.

One hatched the night before yesterday.
Three hatched yesterday.
Ten hatched overnight.
Four hatched late this morning. (one marans- the only one so far)
The only eggs left are the marans.
There are 6 eggs and 3 are chirping. No one has pipped.
This morning, none of these eggs were chirping.
At lunch none were chirping. Now 3 are.
Should I wait 12 hours until a pip???
I don't want them to run out of air.

This is day 21. And yes, I counted the day I put the eggs in as day zero.

I'd put a safety hole in. I usually do for Maran eggs because the shells are so strong, the last time I didn't they died in shell (DIS).

My Marans have always hatched a day later than my other chicks. I'm not sure why, but they do - maybe larger eggs or slightly slower development. It should be 24hrs from internal pip to external pip, so keep a close eye on them. I've never had to hatch any of mine out by hand, but I know many people do aid in some way.

Well I got 5 out, I pipped 3 myself. Two didn't make it- one fully developed chick-seemed Mal positioned, and very big- I couldn't have imagined it moving in there at all. Fully grown, but stomach not closed/ yolk not absorbed. The other looked like maybe it stopped growing before lockdown.

That is very helpful information to know that they hatch late.

I have more in the incubator, this was sort of a test run.

how do I tell if its pipped internally? they are so dark- what can you possibly see?

With dark shelled eggs, I can’t see anything. When I first set eggs under a broody, I candle and draw a line with a Sharpie fine point pen over the air cell. Every time I candle, I redraw the outline of the air cell as it gets bigger and bigger. If I suspect it’s delayed hatching, I tap and listen with the egg close to my ear. If the chick responds with peeping, I put a sewing needle to the edge of the traced line of the air cell, needle aimed *parallel* (not perpendicular) to the shell aimed towards the blunt end of the egg, and gently scratch a tiny hole.

and pierce the membrane too, right?

Once they are peeping, they have pipped internally. I can often make out the irregular shadow with a strong light where their beak has entered the air cell.

so if I dont hear peeping yet, and no pip, but when I hold it to my ear and chirp, I can hear movement, like a faint tap, that doesn't mean necessarily that they have pipped internally-? but if I hear actual chirping it does? is that right?
