cannot be zero at every point throughout such a change
But no one is talking about every point. If you can only detect delta Y for large changes in X, it does NOT imply that small changes in X will also cause some changes in Y. Step functions are common in reality.
In this context, chicken production utilizes economies of scale. This means that a “unit” of chicken production is quite a large chicken factory. To change the number of chicken factories, you need a sufficiently large change in the relevant factors—if the demand drops by 1 chicken, the number of factories won’t change.

And if you don’t know where the step is, this applies.
I think we’ve come full circle here.
This applies only if you are confident that your action is just one out of a large number of similar actions.
In any case, yes, I think we understand each other’s positions and just disagree.
My “not buying a chicken” seems like it would look very similar to anyone else’s “not buying a chicken”.
