Can someone recommend some good ground bird feeder? I recently bought one made from ploy wood which is a plastic material but noticed a lot of peeling and splinters of this material all over the feeder including the tray which is dangerous for birds to eat from since they can end up eating that material. I don't even know why they are using this material to make ground bird feeders. Just right after I bought it I told the seller to make there are no scratches, no peeling, no damaged or defective parts. I spent 40 minutes using a tweezer just to try to remove the peeling from the tray and a lot left including all over the bird feeder so why are they even selling this product if they know it's not safe in the first place? Is it safe?
