And pen, and egg thing.

Have no idea as to what the back side of your egg thingy looks like, but guessing without seeing it, I would say it is either a feeder or a waterer for a birdcage.

Yes! ....the egg thing looks like it goes on the side of a bird cage. I had one that looked just like it from that side!
