looks like you have already figured it out seeing as how it says you bought a few, but I'll clarify just in case anything might be confusing

If you go to my stable

http://www.sylestia.com/view/stables/?userid=3027 Everything in tab 5 in yellow is for sale. (click tab five to get there)

Click on the pet name you like

Click view prices

click purchase

If you go into the hatchery http://www.sylestia.com/view/hatchery/?userid=3027

Anything with the little gold coin with an s in the middle of it in the top left corner is for sale.

Again, just click the pet name

Click view prices

Click purchase

On the top part of the hatchery in the right hand corner is a set of numbers 1,2,3,4,5 These are the pages. You can click through the pages to view more pets and anything with that gold coin is for sale.

Works the same for everyone

Hope that helps and welcome to sylestia!
