Hi, I'm reading the McMurry catalogue we just received and inside they have several types of feeders, but one comes highly recommended. Its a 4 inch high by 4 ft long trough with bars in a gothic shape that separate the trough into maybe 5 or 6 sections. They say this type has the best results for not wasting feed. The other is like a bucket with circles all around the rim. Like the kind used for baby chicks, but with a five gallon bucket. I guess my question is...do any of you have experience with these? Have you found your homemade PCV pipe feeder or other kinds to be just as effective? Any thoughts on this? I hope I'm not repeating any recent post questions.
