I suspect they're mainly concerned about turning the genes for teeth, long bony
tails, and wing
claws back on, to make a stereotypical small non-avian theropod.
Pygostyle-like tails, toothless beaks, and reduced forearm claws were all
present in various non-
avian theropods; so as you've pointed out, chickens are already 'nested' quite
theropoda (if you'll excuse the pun).
You'd probably get a more dinosaur-like result from retro-engineering a
cassowary - although I'm
guessing chickens are a lot easier to work with in the lab (and a lot less
likely to disembowel you).
