  Hi Em,
  
  That would be the one I made my genetically modified chicken! We were studying the genes necessary for chicken feather development. I injected some virus into the chicken embryo to remove a gene that I believe is important for feather development. The egg was hatched as usual. The chick turns out to have much less feather than the normal ones! It is normal in other aspects.
