They have a bunch on ebay for sale. Price can vary from 12 and up an egg typically. Of course then you have shipping, but check around and see what it adds up too. Getting them closer to you does up the chances for a better hatch......
I paid as little as $10 for one on ebay before (didn't hatch), I know of a farm that sells day old chicks very cheap & I was very satisfied with them. They charge $40 a chick with a minimum of 4 chicks per order. Shipping was $20-$40 too I believe, hatching season for them is over until next year. They do have a website & they're called Scattered Oaks & located in Texas.
I sell mine for $25 an egg. I sold them last year at that price....Shipping was extra by $7-10 depending on where I sent them too. I can go as low at $20 and egg.
