thanks Ken for starting this tread, i too want to be able to keep livestock unattended for long period of time. i can rig some things up to provide food/water for them for the period of 2-3 weeks but i have issue with keep my chickens alive. i do have electric fence for the coop area, but some of the chickens flew out but does not know to fly back in. my neighbor said to clip their wings but i want them to gather they own food if they wish to during the day and get back in to the coop at night. i have different issue with ducks, the pond get dirty less then a week, i been tried to flood it out and replace with fresh water from the creek but it become a task to do. goats seem to be keep them self well in the wooded area then again i have not leave them alone for more than a week yet.
