I'm outfitting my recently delivered coop with the essentials before my first flock is old enough to move in. I'm planning to put a tray/board of some kind under the roosting area in the coop for easy cleaning - seems like a common practice. What kinds of trays (purchased? DIY constructed?) are you using. Trying to determine the best solution for my coop. it's a 6x6 - roosting area is about 60" wide x maybe 24-30" deep. Obviously one nice, perfect, right sized tray would be ideal. Thanks in advance for sharing your solutions or sources!
