Do you find any problems having the nesting boxes on the ground like that (other than having to bend down to get the eggs)? I like the simplicity of this design. Does the other side look the same? Do you have any more pictures?

It is my understanding that chickens don't wrap their feet around a branch like exotic birds. They like to sit on them. If the weather gets really cold where you live, then flat is definitely better because their toes could get frostbite.
