The short answer is: No, they dont have the same finger prints!
They're very similar, but your finger print is not solely defined by
your genetics. It is mostly, but small parts of it are defined by your
environment. For example, the temperature and nutrition can change your
prints. Anyhow, here's some info about it.

No, temperature and nutrition doesnt change the DNA - but it can change
the growth rate of the fingers and affect the way the genes are
expressed. If you're interested in the effects of the environment versus
the effects of the genes on an organism, well, you can join in on the
debate (: People have been arguing about it for a long time. Do a google
search for "nature versus nurture" and it will come up with a stack of
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.
