If you cant personally handle the rooster and dont think you will be able to learn how to handle it then you should either find a new home for the bird and be very truthful about the situation or you should cull the rooster. Chickens are livestock, they were selectively bred to serve a purpose and that selective breeding included tonssss of culling, it is not cruel to cull. Imo it's more cruel and very irresponsible to randomly dump a bird off at some "place"
