It seems not so many people realize the already "old" science.
5 years ago we (and we means me and some of my colleagues) were producing chimeras for genetic research. We were implanting cells from a Quail embryo into a Chicken embryo.
The reason for that was to be able to follow/track the cells of the Quail in the new host, the Chicken and observe the interactions.
Now, we only did this at the embryonic development level but other scientists did go all the way 'till they hatched.
One of the "not so expected" results was that the new chick was singing and behaving like a quail (this was due to the fact that the transplanted tissue was nervous tissue - neuroectoderm).
I am not aware of natural chimeras like this but it it possible. Evolutionary accidents sometimes lead to a new species. Despite the fact most of the mutant individuals are not fertile to spread their new genes.
