You do not get a Red Junglefowl laying a 2000s definition of a chicken egg. You get a Red Junglefowl laying an egg with a mutation that that "Red Junglefowl" will pass on.
Every generation the Red Junglefowl becomes closer to the 2000s definition of a chicken.
It wasn't a "mutant" in the sense that one Red Junglefowl was born to create the chicken egg what we know as a 2000s definition of a chicken.
My favorite thing is "We wouldn't have had the technology to go to the moon in 1969"
So Apollo 12 (1969) 14 (1971) 15 (1971) 16 (1972) 17 (1972)
Were all fake too?
So we faked the first moon landing and then proceeded to fake 5 more moon landings in 3 years?
That sounds real smart
