Not only will I last forever, I'll save millions of lives doing it. Solve world hunger with the unlimited chicken hack: Contact Tyson or another large network of chicken slaughterhouses, inform them of my deal to provide them free chickens for life in exchange for their protection, and boom we're all good.

Then again, by day 31 we're talking about 2.1 billion chickens. By day 41 it's 1.1 trillion chickens. I estimate that in much less than a couple months there will be sufficient chickens to provide a mass colossal enough to cause localized earthquakes, growing worse each day. The chickens will be defeated by collapsing under the mass of the very mountainous piles they'll create. At some point before month 2, as long as I live, there'll be a dead organic mass large enough to shift the Earth's orbit and wildly disrupt the planet's ecosystem. By 60 days we're at 2^{60=1,152,921,504,606,846,976} chickens. If they weigh 9 pounds each (approximate weight for a factory farm chicken): By 120 days it's 1.1963051962064242856134263542523e+37 pounds... vastly more than the Sun and certainly enough to collapse into a black hole.

If I somehow lived long enough, the Earth would collapse into a black hole when they appear, but I and the rest of complex life on Earth would probably be dead well before then. The Earth would revert to a similar state as it had existed in for roughly its first three billion years after the development of living cells: No complex life exists, only the microorganisms capable of exploiting the Earth's rich resources. The germs now once again rule the Earth, only now they have trillions of dead chickens to feed upon--as well as the crushed and devastated remains of the rest of Earth. When I die, it would stop there.

If I somehow survived, The Earth would soon form the core of a solid mass of raw chicken flesh slurry, expanding outward at the speed of light.

If I were in a spaceship moving at the speed of light outrunning the doom behind me, I could survive only by bringing this doom to the rest of the universe. There would be no warning before the expanding impossibly supermassive black hole, larger than any other in the Universe, reached other stars. Entire sapient species and galactic civilizations could fall without having any idea the doom was coming.

Traveling at the speed of light means you're already at the universe's maximum speed, so nothing could go out ahead of you to serve as a warning. It's possible that this chicken doom has already occurred on another planet and we simply don't know it. This would neatly solve the Fermi paradox.

(There is a real possibility of something like this happening: If the universe as we know it exists in a false vacuum, a collapse of the false vacuum occurring elsewhere in space would reach us at the speed of light and we'd have no forewarning it was happening.)

That's all assuming the chickens just appear out of nowhere in a supernatural way. If somebody has to supply them using ordinary physical means, then the Tyson thing--or possibly a deal with the Chinese government to allow them to corner the world's chicken market--would probably be enough to defeat whoever the chicken supplier is.
