I'm pretty sure that a dinosaur had started laying eggs down in the nesting boxes in the pasture. As you can see below, there was a chicken-sized egg without a shell among the rest of the eggs. You can get an idea in the pic below of how leathery the egg is; I'm fairly certain it's a dwarf T. Rex or possibly one of those spitting lizards off of Jurassic Park. Chickens are pretty much diminutive dinosaurs with feathers, so understand why a dinosaur would want to hang out. But as tasty as the hens are to all the other forest critters, I just can't figure out why the T. Rex hasn't eaten any of the chickens. Maybe a Pterodactyl?
