Is it possible to have 3 hens and get an egg with embryo inside?

It's not possible to have three hens and get an egg with an embryo inside.

Here's why:

* One hen lays an egg at a time. A hen can only lay one egg at a time, even if there are multiple hens present.

* Fertilization is required for an embryo. An egg needs to be fertilized by a rooster to develop an embryo.

* Hens don't fertilize eggs. Hens don't have the necessary reproductive organs to fertilize eggs themselves.

Therefore, you need at least one rooster and one hen to produce a fertilized egg that can develop an embryo.
