Regarding these DIY Chicken Feeder PVC Pipes, How long does it last? I will mostly like build one similar to the picture below. The reason why I asked is because I just received a job position that is 100 miles north in the city. The pay is awesome roughly about $5,000 a month I'm starting next week!!! I was on vacation the past year so looking forward to getting back in the work force! My concern is since I will be not home for a week, I will be staying in a small house weekly and returning to my home 100 miles away on the weekend only. I need to devise a feeder type system for my chickens and a water system as well that will last 5 days of no human interaction. We'll maybe if I can get a friend to go over to my house and feed it once a week maybe mid week on Wednesday. I have a week to figure out a way to make such device to keep them fed for a week if worst come to worst. How long will these setup last? Let's say, it's 4'' in diameter pipe, and I would like 4' feet tall. Let's say I would be using 5 or 6 of them just like in the picture.
