Im finishing the final details on the coop before getting my first flock and decieed to put in a rain barrel colleftion system. I have the collection part done and will be running a pvc pipe with nipples into the coop and run. This is what i have so far... This is the front of the coop. The gutter attaches and drains to 1.5" pvc It then goes down the side and connects to the rear gutter downspout Finally making a 90 degree turn and filling the 20 gallon barrel from the top The barrel will have a ovc pipe coming from the bottom that will run througj the wall of the coop, have a few nipples installed and then go into the run with another few nipples. I hope to get that part done shortly and will update this thread then. If anyone has any helpful comments or suggestions, I'd welcome input on the setup.
