so I am thinking about getting a few chickens for eggs, again, and i want to keep them in a cage because I had problems with dogs getting them or running off or not being able to find the eggs. so I am thinking about using something like the picture . all the feces falls through the screen making it easy to clean. maybe make it so the wood is directly under the mesh and can be removed for cleaning. as for the size I am thinking 3x8' floor and 3' tall. this would be for 3 hens. all of the ones I have seen on the net have some kind of enclosed area is that required? I live in hawaii so cold isnt really an issue. what do you think? I dont have a flat lawn so I cant use one of those tractors.
