I have no research whatever to back up my theory, but, as it happens in other species, I would predict it could happen to chickens.
We humans have probably caused prion diseases in ourselves ( an outbreak of kuru, a degenerative brain prion disease in Papua, New Guinea in the 1920's was considered to be due to cannibalism....eating human brains in this instance!). Prions survive cooking....hence BSE (mad cow disease) probably transmits to humans from eating meat as Kreutzfeld-Jacob Disease. These diseases jump species as well....so better safe than sorry.
Personally I don't think it's worth taking the risk when there are so many alternatives available, and I am unashamedly biased.
