Duck help

[Big Flounder]

My daughter has more love for animals then any person I have ever known and it breaks her heart to know that one of our neighborhood ducks seems to be losing his bottom beak and is having trouble eating. Not sure how it happened but my girls feed these ducks like clock work every day and protect there eggs in our flower beds. Well I just got home from work and my youngest is in the yard feeding this injured duck and crying again. Do you guys know anyone I could call to come get this thing or somewhere I can bring it that would be free? I don't even know if it can be helped. I would love to make a good gravy with it but my daughter would never forgive me.
