If you want to do a trial on shipped eggs, maybe try with the trade thread, that way you will send them something for the eggs? Or even go on e-bay and find something cheap that the most you wont be spending over $15 including postage, and have it as a trial. However I would recommend trying locally first. I spent about $100 this year on eggs through e-bay, that included postage. However I forced myself to stop, otherwise I would have bought way more then I did. But you have to limit yourself. I didn't last year and I lost lots of money in spending and believing a hatchery was better then an e-bay seller. well we shall see. I am fairly sure that the e-bay eggs will be just as good and maybe even a few extra chicks then what I got last year.
But I still say check locally even try craigslist.
