It seems logical to drain your bird bath when the weather turns icy cold, but birds that stick around Ohio year-round still need water in the winter. While it’s not critical to always keep bird baths ice-free in the winter, your backyard birds might find it helpful to have access to a bit of water when everything else is frozen over.
The easiest way to provide water in the cold outdoors is to replace it daily, or a few times a day, to prevent freezing. Another option is to keep the water moving with a small mister or dripper that can be placed in the bird bath. If you want to keep the bird bath completely free of ice this winter, you can go a step further by equipping your bird bath with an immersion heater. But whatever you do, never add antifreeze to your bird bath, as it could harm the birds.
