Here's a fun thing about ostriches....they live in a harem arrangement....one male and a group of females. The girls scratch out a communal nest and lay their eggs together. They take turns sitting on the nest.

Now...there is an ''alpha'' female, and if she somehow determines that there are too many eggs to keep warm, she'll remove a few--but she somehow knows which are hers and eliminates those of the other girls!

Ever noticed that male ostriches are black and the females are lighter/brownish? That's because HE sits on the nest at night and THEY sit on it during daylight. Camouflage.

Ostrich eggs are amazingly strong. I saw a man in South Africa who freely admitted he was "close to" 300 pounds as he STOOD on an ostrich egg. It didn't crack. Consider the size/weight of ostriches and you'll know why the shells need to be so durable.

Yep, ostriches just run, or kick to kill.
