In addition to chickens, another bird that is a potential candidate to be reverse engineered into a dinosaur would be the emu. I found this video that truly highlights the dinosaur in them, waiting to wake up. Even though emus are still birds, there is still a considerable amount of dinosaur in them. I wonder how much of their prehistoric instincts would be awakened when their genes are reverse engineered. I will tinker with this concept further in my new dinosaur book.
