I’ve done that very thing, as well as feral pigeons in daylight sans the nv. I have three PCP air rifles, lots of fun, extremely accurate.
It amazed me how they were picking the rats off one by one and the rats just kept walking around like nothing was going on. There was a whole line of rats going across a wall and these guys just kept picking them off and the rats just kept coming.
Must be like it was a the Frozen Chosin, except the rats ain't tryin to kill ya.
