And that's the key thing for an egg.

An egg has to be permeable so oxygen can get into the developing chick and then there's kind of a support cup around it.

And I did go down a little bit of a YouTube video hole last night.

You can actually apparently hatch a chick in cling film if you really want to.

So this may not be such a big...

Look on YouTube.

This may not be such a big breakthrough, but a lot of those, even though you can hatch a chick in lots of different types of membranes, they're often not very healthy because they don't get enough oxygen.

So, I mean, while this is a press release, it may be interesting because the idea of an artificial egg, while it might not be helpful to bring back the moa, and many people in New Zealand do not want that to happen, it might be helpful when you think about more ethical farming practices or indeed to support species that are still alive who would need additional support.
