When I first started out with my backyard flock I had a standard, Little Giant hanging feeder. Worked great besides for what seemed like a large amount of wasted feed. I then switched from layena crumbles to pellets. Yes I saw a slight decrease in wasted food, but still waste none the less. So then thanks in part to many members of the BYC forum, I set out and built my own custom no waste feeder. Which to say the least has worked very well, until recently. With my custom feeder I still use Purina Layena Pellets, and until recently was having great success. My problem now is my creep style feeder jambs, due to what seems like overly dusty pellets. I have now started to pre-screen my pellet feed, to get this for a lack of a better term dust out of my feeder. Is anyone else experiencing what seems like really dusty Purina pellets. I have used Purina since day one, and buy from Tractor Supply, not sure if the new oyster strong Layena pellets is my problem or what. Any advise, maybe on a new feed brand, would be greatly appreciated.
