Basically if you start up with a few chickens with the ability to produce the protein they'll reproduce to give more of the little beauties. Just think by using virus's there is all the hassle of sorting out the genetic material to make them less harmful and there is always the possibility of immunity - in that case a new virus will have to be sorted out. People cannot become immune to chickens as far as I am aware and they are relatively cheep to keep... if you'll excuse the pun.
