If such a metal screen were feasible (see the subjunctive there? :D) then one would expect planes to have them.

This were discussed (now if I only were sure this is grammatically correct) back when Captain Sully ditched that plane into the Hudson after initial encounter with goose. Turns out, it’s not feasible. See this post by **aerodave** for detailed discussion, the introductory part of which I quote here:

Any screen more robust than some flimsy chicken wire will produce unacceptable pressure losses in the incoming flow. Airlines depend on wringing every last bit of efficiency possible from their engines, and the performance hit from a FOD\* screen that could stop a goose would be massive.
