Here is a photo of the cattle panel chicken tractor I recently built to house 25 Cornish Xs. The birds will be in our back meadow in about a month and we have fox, bear, 'coons, weasels, etc. that I really don't want killing my flock before I get a chance to. I am putting extra chicken wire on the door and back panels but I'm afraid of predators digging/squeezing underneath. Would a chicken wire skirt work better than covering the bottom with wire? This has to be mobile as I expect to move it several times a week and don't want the wire getting caught in the grass and want the flock to be able to 'free range' as much as possible (as much as Cornish Xs do ). Any suggestions would be appreciated. Photos of solutions are particularly helpful!!
