Knock on egg and listen: 3+1. You tap on the egg's shell, listening carefully to the creature inside. It doesn't exactly knock back, but that does cause its scuffling to renew, apparently giving it a burst of will to resume trying to get out.
Egg hatching: 1. Unfortunately, all that does is exhaust it. It goes completely still after a moment, making no noise. The shell is completely unblemished on the outside.
Crack the shell: 5. You pull out the handy shell-shard you'd kept with you, biting your lower lip, and set it to the surface of the egg. You use a stone in your other hand to tap it like a chisel, so you don't hit too hard, being as careful as you can. After four or five taps, the tip of the shell breaks through the egg, cracking it.
Egg hatching: 5. That crack is all the creature inside needs. With a hard shove inside, it splits the shell, knocking a chunk out of it. After that it rests, the hardest part done, sticking its nose up to the hole to take a breath.
Identify: 2. You have no idea what you're looking at. It's got a beak, of sorts, though when it opens it a bit to breathe in you see little saw-teeth set deep inside it. It is bald and its skin is very wrinkly, suede-like, and a dapply gray-brown color. As it finally crawls free of the egg, you see the rest of it, but you are not really sure what to make of it.
It honestly looks rather ridiculous. Its body is fat and stubby, but limbless, with a fairly short tail and short neck. It has almost no features, other than the beak and teeth. No nostrils, no eyes, no evidence of ears. It does have bones, and a distinct skull, so it's not a worm, but you are hard pressed to say what it really is!
And then it starts to squawk piteously at you, though you're not sure how it knows you're there. You need to feed it something. You have no idea what it eats. You'll have to try something and see what happens.
((As outside knowledge for you all, as I figure it'll aid you a bit without completely ruining the fun, this creature is undefined. It is nothing yet. It will become something based on how it is raised and cared for, and it could change extremely radically from its current simple form. Every decision, from what you choose to feed it to where you keep it day to day to if you talk to it or train it or what have you, will affect what it becomes in some way. However, you don't know what will do what, and you can't just assume something basic like feed meat = becomes perfect hunter--It's going to be a little less simple than that!))
