If they don't also sell Easter Eggers then they're Ameraucanas are probably Easter Eggers. Especially since it says they can lay green eggs on the site and says the birds are multicolored.
"AMERAUCANAS
Ameraucanas, known as the "Easter Egg Breed", are a multicolored breed. They have beards, muffs and a normal tail with a tail head. They are often incorrectly called Araucanas, which have ear tuffs, are rumpless, and do not have a tail head which gives them a bunny tail appearance. Most of the chicks sold as Araucanas are really Ameraucanas, which are excellent, efficient producers of large eggs of many colors and shades including blue and green.
Standard weights at maturity are males-5 lbs. and hens-4 lbs."
The pictures also look like Easter Eggers, the chipmunk chicks and stuff. True Ameracaunas only lay blue eggs and they would not be multicolored or sold as just "Ameraucana"; they only come in certain acceptable colors so would be sold as such. I think some of the colors are black, blue, splash, buff, etc., I will find a list.
Awww poor thing. So sad yet so sweet. And poor you!! I am so sorry.
