Drag and drop egg group onto new layer’s icon so you will duplicate it.

Now hit [Ctrl] + [E] and your group will transform into one layer. And that’s what we need. It’s good to work with groups. You don’t have to name each of layers then when you work with large files. Just look for group and then for thumbnail. You can also [Ctrl] + [Click] on the image when you have move tool active, so you will be redirected either to your group or directly to layer (depends on your settings).
Step 29
So I assume you have egg on one layer (leave shadow and background separated). It’s good to make a copy of egg layer before we will start to do anything. Now pick the polygonal marquee tool (in fact you can use just lasso tool, it is just my preference) and make a selection that simulates small hole in the top of egg, like this:

And press [Delete] key.

Step 28
Now create another selection:

Go to Edit > Transform > Rotate, move the rotation point to the bottom left corner:

And then rotate our selection a bit:

Do the same on the opposite side of the hole.


Step 29
Now we will try to add some 3d effect to our eggshell. With polygonal lasso tool create selection as follow:

And fill it with a color #97612e. Remember- do this on new layer and place it underneath the egg layer. You will get this:

Now to the same to the other parts of eggshell. Try to visualize it- how it should looks like. See how I made it:
