While you’re at a hardware store, pick up six pipe elbows and six pipe end caps.
These holes should be located near the bottom of the bin. The marks should denote where the saw should start. [4] X Research source
If you are using a smaller bin size, you should use a lesser amount of openings as best suits the bin. It’s a good idea to spin the hole saw in reverse. This will result in a cleaner cut.
The “female” end of the PVC pipe should fit on the inside of the feeder bin.
This may be done with a precision knife. It’s good idea to sand down the edges you cut to prevent roughness. Offering a “window” (rather than an open hole) will prevent the chickens from unnecessarily wasting the feed. [8] X Research source
