Weird... I think he more or less believes what he's saying, if you look at some of his other videos, he DOES seem to have an interest in poultry (and car crashes). Looks like he has hatched quail (in incubator, not cups!!!!).
Ummmmm, I think he obviously left a LOT of info out, like.... temp/heat source! ????
Weird.
If anyone managed to get some development, I bet it would end up a horrible mess... I can't imagine veinous development successfully attaching to a paper cup instead of membrane/eggshell...
