Some of the chickens have mastered the grandpa feeder. A grandpa feeder is basically a box with a lid on it that you put food in. There is a step that they stand on and it opens the lid. Now under normal circumstances it should take a few weeks for chickens to learn how to use it. Not mine! It's been months - LOTS of months. I'm not even sure if they can all do it, but Bubble and Squeak and Sparrow and Abagail can. (eta. Millicent and Maude as well!) I've been spying on them for ages!
I obviously have incredibly thick chickens. It is a huge bonus that they have learned, though, as I was feeding the sparrow, mynah birds, kingfisher ( didn't mind this one!) and every other small bird within a 20 mile radius. They queued up in the morning just waiting. What was even more frustrating was that the chickens had learned, that if I didn't put the clasps on properly on the grain box they could just jump on the lid a few times and the lid would fall into the box and they could stuff their faces. They could learn this but not how to eat out of the grandpa feeder! Go figure!
I have this feeder

I'm reckoning a sack of food will last twice as long now. You get aluminium feeders like this as well so I think I may get one of these for outside.
