OK - I can't wrap my head around this idea. How in the world does a hen move an egg? I keep reading random posts about broody hens stealing other eggs, relocating nests etc. They don't have thumbs! I've seen penguins put the egg on the top of their feet and shuffle around with it. I have seen hens rolling the eggs aroudn with their beaks. But how would they actually get an egg from one nest box to the other without breaking it? Has anyone witnessed this?
