I have been wanting to have some hanging feeders because I have mice and they kick out so much feed. The ones available are way to big for my little coopettes. I improvised on a feeder a friend made from PVC Pipe and used storm drain gutter. This was a piece of cake to make and I am looking forward to hanging them tomorrow. I got the parts at Home Depot, Lowes had a different type. These have a nice lip on the top and I think it will help keep the birds from throwing out the feed. The pvc came in 8 or 10 foot lengths I have seven feeders of various lengths from the piece I bought. The end caps come in right and left pairs. Those were the most expensive but the interlock and the ends have a putty already installed on the insert part so they fit nicely and will not leak. These could be attached to a wall as well. I just need the chain and a hook and I will be good to go.
