Congratulations on beating the odds, that a lot of hybinos.
I don’t think much work has been done on twinning in egg-laying animals.
It could be both that two ova shelled together or a single ovum that gets split. I think its most likely that two ova were shelled together (like when a chicken egg has two yolks); if there were a single yolk sac I doubt that both fetuses could develop to term because they would have to share nutrients and there would not be enough for both. Which means you may be able to figure it out by looking at the egg and seeing if there are the remains of two yolk sacs or just one.
I also think that deformities would be the norm in twins from egg-laying animals. There is a finite amount of space to develop into in an egg; since a lot of development is dependent on information cells receive from the environment and other cells, changing either of those things would be bad.
I would love to see pics of twins after they are out of the egg.
Just my thoughts on the subject, Cheers, Vinny ----- “There is a grandeur in this view of life, with its several powers, having been originally breathed into a few forms or into one; and that whilst this planet has gone on cycling according to the fixed laws of gravity, from so simple a beginning endless forms most beautiful and most wonderful have been, and are being, evolved.” -C. Darwin, 1859
