Please do not purchase these chicks. I have read through the thread and it is 100% a scam.
And, yes, scammers will keep contacting you and justifying and trying to get you to believe them until the moment they get your money.
I was just scammed this past fall with a golden retriever puppy. He had a website with testimonials, was local and I spoke with him on the phone and through text messages (even had a local number). I found him on a local newspaper's classifieds (the actual paper, not craigslist or anything like that, so he had to pay to advertise). He agreed to accept paypal goods and services, deposit down to reserve the puppy and the rest when we picked him up.
Gave the deposit, and the scammer dropped off the face of the earth. While filing my complaint with paypal, I found that he posted the same ad less than a year ago in a TX newspaper. Scammers are getting really creative at looking legit.
If you do ever decide to take a chance on something that may not be legit, insist on using paypal goods and services because you can easily file a dispute (even though it took over a month for us to get our money back). Paypal friends and family, you can't.
