Been meaning to post this up for a little while now, because on my searching I found just about nothing on DIY feeders for a number of birds.
Ever since my aviary rebuild, I've been trying to find a feeder that works for me and my birds. Tried a chicken hopper, and had a lot of problems with getting the seed to come out and managing to hang it without it breaking. Tried a tray, had problems with wastage and the birds fighting. Tried multiple small hoppers, and I couldn't keep the seed up to them. Plus, there was the ever-present issue of mice.
I got an idea one day that I had no idea whether it would work, but if the last couple of weeks are anything to go by, it definitely does.
This is what I made.
It's not pretty by any means, but it works! One of the end caps comes off the pipe and unhooks from the wire suspending it (the wire is going to be replaced with chain or similar, we're in the process of working out the best way), allowing it to be lowered into a bin to empty without making a mess. I've seen almost every single one of my 18 budgies using it at the one time, with only minimal fighting. And, no sign of mice activity! It's solved just about every problem we had.
It was pretty easy to make. We recycled a DIY PVC pipe fishing rod holder my dad had made a few years back; it had one end of the pipe blocked off already which worked perfectly. Using a grinder, we cut halfway through the pipe, leaving a centimetre or so from the caps/end to keep them on. From there, it was just a matter of cutting lengthwise, smoothing the edges and hanging it.
