I no of a man that feeds deer sheep nuts.
Thats the way to do it. Build in a hopper so you don't have to fill every day. Pressure treated wood and a sheat of ply and your sorted.Craig, why not use Mangers.
When I was trying to get some pictures of activity in a particular wood a while ago I made some mangers from ply and of course they have roofs so are safe from rain, and just put wheat in the food cradle.
Just off the ground to deter Badgers, mice or rats but they still got at the wheat but not enough to worry about, mind you wheat at the time was less than £100 a ton then.
That's the sort of thing but maybe not quite so elaborate size wise.Like this ? http://www.buckmanager.com/
