Dragon Cave-Have eggs or Dragons?

[starmom]

Somehow I got 2 paper dragon eggs! Woohoo! So since they can't breed I'll freeze one of them as a hatchling.

I think after that all I need is silver & gold to have all the regular dragons. I'm not trying to get the dinos or the chicken. And I don't count Christmas dragon (for now) since I started long after they were no longer available.

Then are the "SECRET" dragons. Have any of you tried to get these?

But, you don't have males and females of each type
How can you breed? Also, what good is freezing? I think I missed something
