If you click on one of my dragons it will take you to a scroll and at the bottom it has a link that says get your own. But to make it easier I'll just post the link it's here
http://dragcave.net/
Now, here's the thing there won't always be eggs there and when their are they go fast. They appear on the hour at five minute increments. So they'll be there at eight and then at eight o five, eight o ten, etc. It works like that.
Some times there will be a link at the cave entrance that says you can adopt an abandoned egg. Those can appear at any time because it's people who abandon them.
It may take you a while to get an egg. It took me a while to get my first one. But it's fun once you actually get one.
Once you get one you'll get a page with codes on it just pick the one for forum signature and put it in your signature. There is a thread on here where people talk about them and post their dragons and eggs for clicks. It's called dragon cave anonymous I think. I can't go in that thread because it crashes my web browser. So I can't give you the link. It's in the hangout section of Mene.
Oh before I forget you have to sign up first before you can get any eggs. It took me a while before I got the confirmation email. My yahoo mail worked for it but it took a day or two.
I hope this actually helped and didn't confuse you more.
