I've nearly completed a double decker quail hutch. Each is 2ft wide x 6 ft long. I've designed them to have plastic trays under the hardware cloth floors to catch the...well you know. I've searched everywhere for plastic lids, the kind that would fit large storage bins. On-line and in stores I can't find any without having to buy the bins as well. I don't want to spend more on the catch pans than I spent on the entire hutch. I even posted an "items wanted" on Craigs list with no responses. Any ideas for cheap catch pans that aren't too heavy and are easy to clean?
