Trust me, when it comes down to chickens, the chickens always come first.

Why? Because they are vicious little buggers, and if you try to make them wait they will eat you.

"Oh, hello monkey, is that a treat for me in your hand? How lovely, nom nom nom. What? I took your finger with the lovely dried bug? So sorry. Oh, hello monkey, is that an open wound in your hand for me? Nomnomnom. What? I’m not supposed to devour the flesh from your bones? So sorry. Oh, hello monkey, is that a bone sticking out from where your finger used to be…

You get the idea.

So, I ban say with authority that if the egg had come first, the chicken would have eaten it.
