I may have made that confusing. I do fill my chicken feeders, which are all kept inside the coops/runs. I just don't fill the wild bird feeders out in the yard.
I probably could because I clearly see migrating birds making their way into my yard -- which I generally love. Not filling the wild bird feeders isn't stopping them from showing up.
I quit because there was avian flu in a couple of adjacent counties to mine, and because I am close to a county-owned pond where migratory waterfowl congregate.
Also, keep in mind that I am an overprotective worrywart.
