I'm still making my chicken tractor plans. I will not be keeping their food/water in the house, but want to keep it relatively safe in the run area. I was planning to hook their feed to the side wall of the run or hang it from the top. Will I need to remove their feeder every night? Can rats/squirrels/other beasties get into a hanging feeder? I'm not as concerned about losing the food as I am about sicknesses spread from rats. I'm resigned to the fact that there will probably not be a way to completely keep them out of the run, but I may attach a fine mesh "skirt" to the bottom. There are a couple of "neighborhood cats" that wander about, and hopefully they will help some. I've also read the sugar/oats/plaster of paris remedy, and am only concerned that our neighborhood will become strewn with dead squirrels. Maybe my imagination is getting the better of me.
