I don't know if it affects my contest entry, but I updated my recycled bottle article after making another feed scoop and a dish to feed wet mash to the chicks: https://www.backyardchickens.com/articles/feeders-and-scoops-from-recycled-bottles.76244/
I'm not sure this is eligible for this contest. It's not a feeder or waterer per se, it's a field shelter for them: https://www.backyardchickens.com/articles/an-outdoor-shelter-for-the-feeder-and-waterer.76487/
This article might be too simple -- it's almost entirely pictures -- but I didn't see anything like it while browsing the articles in the Learning Center.
