Lucky you, they take any d*****m thing that might be green here! I net everything that grows if I want to eat it, if the pigeons don't get them the squirrels will. Use some stakes, bamboo, plastic, what have you, and net over these, making a cage - you want to discourage the pigeons not give them a nice place to sit.
If it is still likely to be frosty you can cover with horticultural fleece, but really broad beans don't need this as they are very tough plants indeed.
