Thank you! So, the waterer and feeder were kind of an afterthought; I'll admit. At that point, we were so anxious to get pullets that we thought "We'll just do something simple for now and upgrade once they're here." Being in New England, it can be tricky to find started pullets from a local, reputable breeder once you get into fall and winter.Your husband did a great job on the build and you did a great job on your end! That coop should last a long time!
A few things I noted when looking at your pics.
Your water cups will freeze when it gets cold enough. If you don't have something figured out already for winter, you could make a heated horizontal nipple waterer, I'll add my article link below. You could run a heavy duty extension cord out to the coop for the winter. That's what I used to do, before I moved.
Are your chickens able to use the feeder good? It looks like the elbows are pointed down coming out of the bucket. With that style feeder the elbows should be sticking straight out, so they don't have to go up at an awkward angle and stick their head down.
If you put gamma lids on the buckets, it will make your life easier when filling them up, unless you don't snap them on tight. Gamma lids screw on and off, I have them on my feeders and had them on my 5 gallon waterers, before I switched to bigger waterers. If you do buy them, don't tighten the waterer all the way. Screw it down then back it off a quarter turn so it can vent.
