We are building a new coop this spring and although we may add electric it will still be a distance from my water supply. However, the coop will be close to a newly constructed barn/garage. It occured to me that I could install a rainbarrel on the corner of the barn to collect rain water and use this to supply drinking water to the chickens. Is this feasible? Have any of you done this and does anyone see a problem with this plan? I guess I am asking if this is ok healthwise for my flock. Thanks all.
