Hello. I am a college student and I have decided to do a somewhat unusual research project; I would like to study twinning in birds, examine the DNA of twinned birds or embryos, as well as explore methods of increasing hatch rates for these twins as I understand only about one percent make it. That said, I am looking for fertilized double yolk eggs -or any eggs expected to produce twins, though I don't know how you'd tell with a single yolk. I'd be willing to pay a small amount for them, but hopefully not too much as I am a college student and I am unsure if my college will help me pay for eggs. Donations, while certainly not expected, would make me very happy. Currently all I have is one double sized emu egg on the way and another in discussion as I happened across a few and got the idea for studying twinning from a couple articles I found on the internet showing that the first surviving and confirmed avian identical twins were emus. I'd like to get eggs of a species that can actually be observed while it is developing, though, and besides I don't know of any other species that has been studied in quite the same way -which means, hopefully, mine will be all the more new and interesting should it have any success.
