I am just wondering if the pvc feeders are effective in less waist of feed? Seems like doing searches and all I am finding alot of these in peoples coops. I am looking for a simple way to feed alot of birds in individual pens. Does anyone have any ideas for someone feeding 30 plus roosters and a system to simply feed them all? looking for a belt system or something that drops food in each feeder from one place. Confusing I think but I hope it is enough to get the idea
