I do not have an excessive Poop problem with my CXs.
I severely restrict the feed to them. I have those movable pens/tractors. The boxes in the background, are for other birds. The taller one is for the Sussex for winter. I have a removable panel on the south side, you cannot see it) So I can reach in scrape poop and check on them if I do not see them for a few days.
The short grey one with the "tub" on the top is going into the shed that is for babies when they first go outside, I was using it for the Sussex's until the other day when I got there "new" redneck area done. It will go inside until next spring now.
The CX's are with Bert Jr in a townhouse. I have a 4x8 single story box and a 4x4 box hooked to two 6x8 runs (covered) however, I still let them out each day to free range, and I limit the feed to them. It is a guessing game on how much they need, without adding more weight to them. Poop is not a problem yet, but come spring I will be glad to move them!
I am building a taller box to replace the 4x4 of the CXs to give them a 8 inch roost and a nest box 8 inches or so off the floor.
