I assume they're trying to make a joke, as it's too obviously illogical if not. (Admittedly it also seems fairly obviously not funny to me, but that's more subjective than believing that an animal can't "do" anything that it doesn't have a conscious understanding of.)

Or, if a chicken crosses a road and nobody is looking, did the chicken crossed the road?

Yes, I'd say so since the road doesn't have to be perceived by a human to be a road. Does it make a sound?

If a road has not been perceived by a human, what created it?

I meant at the time of the alleged chicken crossing
