I was wondering if there was any information regarding the eggs you can buy in the scale shop. Are the breeds/markings random? Do they even have any? Any information would be appreciated. :)

it's random. Species will be random. The color on the outside of the egg gives you some idea of the colors of the pet. (colors two and three of the pet)

Genes are random too. The more expensive the egg, the more likely it will be showing or carrying more genes.

I haven't bought an egg outta there since closer to when I started playing but if I remember correctly, the egg I bought for under 1000 scales was either a 2 or 1 carry. The one I bought for over 1000 scales was a 1 vis. I think it had a carry but don't quote me.
