Has anyone used the automatic poultry feeder with the lid that opens when a chicken stands on the platform? The feeder is waterproof and can be filled with enough feed for a week or more -- the big selling point to me is that mice, rats, birds and other lighter-weight critters can't get the feeder open, but even a small chicken weighs just enough to depress the platform and open the lid hiding their feed. I have a tremendous problem with mice up to big rats, birds, squirrels, etc spending their time eating my chicken feed. Not only do I not like the rodents in particular, but I'm going through tons of feed. I gather over a two week period (there's a training method), the hens will learn to get on the platform to access the feed. They're pretty darned expensive and I've just ordered one -- thought to ask about it on BYC after the fact. Would be worth the expense if it would solve my rodent problem, or at least cut it way down! Do let me know if you've tried one......thanks!
