One way to disconfirm the scientific hypothesis that chickens cannot fly would be to

ask someone.
look very hard for a chicken that can fly.
simply assert that chickens can fly.
simply assert that chickens cannot fly.

And your LOGICAL answer is?

simply assert that chickens cannot fly.

That answer has nothing to do with a scientific hypothesis.

so which is it?

Do you know what "assert" means?

How would you try to PROVE that chickens can fly?

would it be to ask someone or look for a chicken that can fly. they can fly but to a short distance from the roof top of a house to ground but not in great distance.

to assert means to confirm

Right. Show a chicken flying would be the scientific way to prove this.

ok, then i think it would be to look for a chicken that can fly to prove them wrong

Right.
