I agree about putting the levels closer together and adding feed. I have built a few racks and it seems every rack I build I tend to put the levels too close together trying to save space. I put my food at the back with a stopper bar so only 1/3 of the pan has food over it. It can be difficult to add feed. I find it easiest to add feed when I clean. I take the top tub out and add feed to the level below it since it has plenty of room with the tub above it removed. Other than that I think it looks great.
