We have had banty chickens for a few years now, but not until this winter have we had any problems with mice. Cleaning the coop the other day I happened upon a huge nest right in the middle of the coop about 6 inches under ground. They spread out like wildfire. They were not there a few months ago. What can I use instead of poison to get rid of them. I noticed two of the chickens killed a few, I thought they might take care of more but they have not. HELP! the coop is not that big and the smell is much worse than usual thanks to all the little mice!!!!
