Question about the fingerprint of identical twins

Oh, forgot about your other question.

I dont know much about that, but an interesting question. From a quick 
look aroung it seems that you can have two chicks from one double-yolk 
egg, and they would be seperate. Conjoined or 'Siamese' twins dont 
usually result from eggs and neither do monozygotic twins (i.e. both 
from the same egg). When two eggs are released at the same time, they 
can both be fertilised and the chicken's egg producing organs seal them 
both up in the same shell. Apparently, they usually dont both survive, 
or both of them are small.
