I need adoptable help!

[Aluenda]

Hi! my site is http://capria.nuvarta.com/index.php
Anyway, I was trying to add a new adoptable to my site.
This creature (a Uniy), like most of my other creatures, has 4 stages including the egg. But, a Uniy has 3 Alternate Outcomes; a pink, green and blue Uniy.
The alternate outcomes are visiable at the 1st egg stage- [a pink, green and blue egg xD]

But, I don't see an option to make more than 2 alternate outcomes, and each outcome is a bit rarer than the others [pink is common, blue is uncommon 1/8, and green is very rare 1/15]. And, I also do not see an option to make the different outcomes available in the egg stage. If you need more clarification, just pm me or reply here (duh).

Help? Tutorials? Screen shots? I also reply to pms faster :)

Thank you for all your help! If you happen to help me out a lot, I might be inspired to make a banner/background for your site... ;D
