Hi
I have a barrel on wooden stilts which holds a 20 kg bag of pellets,it has a hole in the bottom which i have a huge tight spring attached from the inside the food falls down the inside of the spring which is pecked by the chickens and releases about 6 - 10 pellets at a time so the girls don't have an excessive amount lying around to get wet or attract vermin...... i then keep excess bags in a store room with other chicken accessories
Hope this is of help
