for the most part wild birs are healthy ive been an avid bird watcher for going on 20 years now! you wont have any problems.
things to watch for 1.) news headlines about sick birds found in your are (very rare!) 2.) a dead bird on the ground (does not nesisarily mean it was sick when it died) just remove it thro it away or call animal controll they will usualy come out and remove it. 3.) if you have noticed several dead birds in the same area with in a short time call animal control they will run tests, they will run tests on any dead bird you find. usualy the dead birds you find on the ground are injured by cats, dogs and left there. some will fly into cars along roads and continue to fly untill they fall due to ingeries.
remember to wash feeders every month, wash hand befor and after you feed them or handle the feeders and/or your chickens too, as wild birds can pick up colds and such from your birds as well! so good clenliness is key to prevention!
