Serving a Ball a room temp rodent is not going to work usually.
I would thaw in water and then change the water using the hot water from the tap.
Then serve in the dark using long tweezers or tongs.
Take the feeder by a leg and make it dance for the snake.
If the snake grabs it still hold the feeder and give it some little pulls as if it is alive and the snake needs to kill it. This will get the snake more committed and in the mindset of eating.
Then leave it in the dark for a good while before coming back to check.
If it didn't eat I would give it a break for a few days as trying often will only add stress to you and the snake.
