I purchased from an Agway in Connecticut. They had the most selection and use two different hatcheries. I'm hoping it's a sapphire olive egger...
In that case, it will definitely be some breed or mix that came from a hatchery.
If Sapphire Olive Eggers have blue feathers all over, like in all the pictures I can find, then that chick (Snowball) is not one. Snowball has some pattern of black and silver, and does not seem to have any blue at all (Blue is a gene that turns black into a gray color, everywhere it is present on the chicken.)
The types I thought I purchased
1) starlight green egger
2) easter egger
3)olive egger
4) prarie bluebell egger
5) blue australorp
6) Golden comet
7) red cross
If you are trying to sort out what chick goes with what type, you could post a photo of each chick, and we could try to match them up.
It would be easier to figure out if I knew which one of the 7 breeds listed above snowball is supposed to be... next time I'll have to think of a way to label them or something
For keeping track in future: maybe hold each chick in front of the sign that tells the breed, and take a photo. That will give you a reference for which chick goes with which breed name. Or write the breed on a piece of paper, stand the chick on the paper, and take a photo that way.
Assuming the labels are correct, that would make it easy to match them with their breeds in the first few weeks. And if the labels are wrong, it would be easier to figure out which ones are off. (For example, if Snowball was sold as a Blue Australorp or a Golden Comet, the label was definitely wrong.)
