I don't know why, but I clicked that link and my virus protection immediately popped up with a huge Ransom Ware (I think it was called) warning upon entering the site.
Edit: I saw the pic before exiting and it really is a good set up. I make it like a kiddie pool so when they hatch they can't climb out, but I always leave my character standing over it and they hatch within minutes. So plop it down next to your work shop or even inside your base so you will be up close to it while you're crafting or whatever, like within 5 blocks of it, and it might be more likely to hatch. I've never had the "HELP, MY EGGS WON'T HATCH!" issue. But I've also never left my eggs and went elsewhere.
Edit: I also like to make the shallow spot where the eggs hatch where I work, but have it connected to deeper water so they can go out and swim in a larger pool with high sides. It's really cute.
