Sexadodeaves Shipping Help

[Chicken Tender 265]

Has anybody used Sexadodeaves before?
I purchased tests for two straight run silkies and I wanted to send them in as a “test” as I’ll be keeping both regardless of what they are but I have silkie hatching eggs I’m currently incubating. The issue I’m having is that I’ve never shipped out of the country before (I’m located in Ohio) and I’m having trouble finding the correct shipping address for them. I’m also unsure of the best way to send them. (Letter or package, USPS or UPS).

I tried to email the company but it came back as undeliverable.

Thank you in advance

I have never used them, no, but I am sure you'll be given instructions once you pay for whichever package you choose. I did locate the address: https://www.sexadodeaves.com/en/faqs/envio/direccion-envio-muestras.html
