chicken feeders come in all shapes and sizes. I have seen them range from about $14 - $60. The one I built following plans on a 5gallon bucket diy web site. It has a 4" 90Degree OVC elbow with the side inside the buckets lip cut off and pushed through a 4" hole cut in bucket and the pvc's cut end pushed through so the cut hole is positioned about 3/4" above the bottom. I did caulk around it to seal it well and haven't had a problem with the chickens picking at the little caulking i used. It holds 25lbs+ of food and can be hung from above so as to take it offf floor. the chickens entire head goes into the bucket so they dont spread it a over floor like traditional type like I used while they were babys (pictured above). No food on floor means less wasted food = more money stays in pocket, also when the feeder is hung from above if you have mice they cant even climb into eat effectively removing your chickens feed from the rodents diet! Last but not least with all the food under the closed bucket lid, your birds food stays clean as well! If someone out there finds or knows a better feeder than this please let me know!! oh BTW at local hardware store the PVC cost $4.24 and the bucket was $4.79 and the lid $1.99 and tube of caulk maybe $1.99 and hold just under 5 gallons worth of food and can be hung anywhere strong enough to hold the weight and is weather proof!
