Underground cave theoryEdit

I see jaggis and jaggias go in and out of thier nests. I think, do they have a secret network of underground tunnels and chambers? Honestly, I think so or at least their is some kind of home-thing underground. Unless if it's a tunnel to a area hunters can't get to. They have to lay their eggs somewhare other than area 6, right? (That hunters can pick up)
