Recommendations for poop boards/trays for under roost

[prwils]

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 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!

How about 2-3 Plastic Jumbo Boot trays, like from Amazon? I saw some measuring 43.3 " x 21.7" x 2".
