So, the PVC feeders look nice and all, but it seems to me that it's too much time, money, and effort to make these when you have a larger flock. I raise 50 meat chickens at a time, and even if they're pasture raised, they still are supposed to have enough feeder space to feed at least half of them at a time. When you start multiplying the number of PVC elbows you need to buy and the numbers of feed containers ... well, all of a sudden it doesn't seem so economical. The hanging feeders that you buy in the store are likewise not a great deal when you take into account the amount of space at the feeder per bird. So the logical thing is a trough feeder ... but how to do it cheaper than buying a brand new trough feeder? Vinyl gutters! Here's what it costs, new: 2 vinyl gutters, 10' (~$8 apiece) 4 cinder blocks (~$1.20 apiece) 1 end cap for the gutter (optional) (~$3.50 apiece) <$25 for about 200 inches of feeder space ... I think that's a pretty good deal. Stack the cinder blocks about 8' apart, two high, with the holes facing each other. Put one end cap on a gutter, if using. Feed this gutter into the upper holes (if chickens are close to full grown). Put something under this gutter to help support it in the middle -- a log, or something. Put food in trough. Lay the other gutter upside down directly over the feed trough. This helps keep the chickens from getting up in it and scratching and pooping in the food. I use the one end cap to help food not spill from that end when I'm emptying the trough in the evening. I get it out from the cinder blocks and then pour it into a bowl from the open end. I don't know if others have done this before, but I've never seen it. Hope it helps someone!
