Hi guys!
Really nice eggs!
As you said, they belong to the chilean tinamou or Nothoprocta Perdicaria! It is (like the name says) originally from Chile.
I am, in fact, from Chile, and we have a chilean tinamou breeding farm with my family! I will be glad to contact people in the US, that is breeding this bird as well!
As a new user i wasnt able to upload pictures.. but if u wanna get some, just let me know!
Cheers
Alberto
