Your dream barn

Since it's raining and the last of the snow is still melting, I decided to start drawing plans for a poultry barn I hope to build next year. I want to put a lot of thought into it.
Would anyone like to share how their perfect poultry barn would be set up?

1st suggestion is make it EASY to clean out!!!!! Then easy to collect eggs. Plus easy to get at feeders and waters.

Walking UPRIGHT room, is always good too. lol. A good easy to load into feed room.

Cool, thanks for your input. My barn will be for exhibition poultry and waterfowl so I want to make sure I have everything thought out because I will be pairing everyone up during hatching season and then having them go into other pens after. We get a lot of snow so I have to think of that when building outside pens so the snow falling off the roof does dot wreck the fence.
