I'm trying to set up a food/watering system for my 3 little ladies in California. My girls have a coop from Precision Pet thats ~8ft L X4 H ft X4 D ft. My priorities for their food and water system is spill-resistance, hanging above ground, and a narrow profile so they maximize their coop area when not in their extended run... I would consider modifying the coop to fill with food and water through a hardware cloth area... but my concerns are mostly predators getting their food/spillage. I don't mind refilling every few days. Any DIY or commercially available solutions you would recommend? My DIY level (much like my backyard farmer level)...is beginner.
