Mice in my coop

[demonic]

My current chicken coop was built into a shed but we didn’t convert the whole thing. Half of the shed is the coop, and the other half is the shed area. They have access to the shed area because the hallway in the shed is basically how they come out into their run. In our shed, we have several suitcases lined up in the back and a bunch of other random stuff and junk. One day, when closing the coop, there was a mouse! It came from the suitcase area and just bolted out! I don’t know what to do. Can they infect chickens? Will they eat the chicken food? If there is one, is there likely to be more? What can I do to get rid of these mice?? I’m not sure if this is in the right thread but I find it as a emergency so yeah. Please reply!

By the way, the chickens have been living in this shed coop for almost a year. Nothing like this has happened before
