Help! Mice are infesting my chicken run. I keep the water/food outside (i dont want food in the coop so please dont suggest it). I have always filled milk jugs with holes cut out for feeding and it has worked perfectly for us, but now I have a significant mice problem. 1st year chicken owner ya know. 
I live in northern Minnesota so I wont get a chance to dig up the ground to place some hardwire for several months. What can I do for now?? Maybe hanging feeders? Or will that just cause more spilled food? The other complication is that I have three full size chickens but also two bantams, so I'd need something that would be low enough for them to get to as well.
Thank you for any advice you have, or recommendations for feeders!!
