Incubating egg with white and clear bubbles on eggshell

[NatJ]

Hello everyone,
I'm sorry I didn't get back to you sooner. I said I would get keep you posted. Out of 18 eggs 8 hatched healthy chicks. We did get rid of the egg with white bubbles on it. I placed it in a zip lock bag, broke it. It had dark liquid in it. The rest we are assuming were not fertile.

Thank you for updating!

We have started another incubation cycle. This time I chose eggs that were round not oval.

About egg shape: what is your reason for selecting one shape or another?

I saw this on youtube. Not sure if it makes a difference but I thought Id try it.

I'm guessing it was the often-repeated story about egg shape predicting the sex of the chick inside? That's been debunked many, many times. Trying does not harm, but no good either.

Or was it saying that egg shape is inherited, so if you hatch the shape of eggs you like best, more of the chicks are likely to lay that shape too? That is true, at least to some extent (you will probably get "more" of the shape you chose to hatch, but you will still get some amount of other shapes too.)

I see. Thank you for the information. I don't mind getting that shape. Do you think it makes a difference in the taste?

No, I do not think the shape of the egg makes a difference in the taste.

Egg cartons are designed for normally-shaped eggs, so eggs with extreme shapes will sometimes not fit well, which makes them more likely to break (extra-pointy eggs or extra-round eggs can have that problem.)

Really extreme shapes might also be bad for a chick growing inside the egg.

But those problems only apply to eggs that are well outside the normal range of shapes. For all the more normal shapes, I don't know of any practical reason to prefer one over another, so it comes down to personal preference whether you care at all.
