I wouldn't recommend buying these with the intent of getting rich. Yes, they can sell for that much right now, but the people are buying them for that and expecting to get that next year for their chicks are likely to be very disappointed.
But if you like them and want to buy them for that reason, go ahead. You might be able to pay for the feed with what you sell, but the only way to even break even as a chicken "hobbyist" is to not count any of your labor as a cost. Since it's something I like to do anyway, I don't have a problem with that.
So, for fun, yes, buy them. As a business venture, not so much.
