I've got the hutch designed with a wire front also. If I had room, I would have made just single-stack pens, let the poop fall to the ground and shoveled it into compost every few days, but unfortunately I have a limited space and have to stack the pens into a hutch, making the poop trays necessary. I was looking for something poop-proof for the trays and the plexiglass being clear just happened to be a bonus. The same with the top, I was going to put a corrugated poly top on it anyhow for protection from the rain, since they offered it in clear along with the other colors I just thought that would be a bonus. If they get half-a-day (or less) of extra light through it before it gets poop-covered then that's just supplemental. With all of that said, I'm brand new at this. If anyone can think of any reason why I shouldn't do it this way let me know. The plans won't be final for a few more days and I can still change the design.
Thanks in advance,
Tim
