ANSWER:

You can either clean it yourself or place the bird food further away from the building so he doesn’t have to clean it. You can’t harm other people just to feed the birds who will find food elsewhere. 

We feed birds by putting food on our window side. Many birds come and their feathers n may be their shit fell down on ground. Living in a building, the haris of the building few times told my husband and son that by feeding birds it makes mess n he has to clean it. As it’s his duty cleaning. But are we sinful for troubling him. Don’t want to stop feedin
