and now for an update:
After using these feeders and waterers for four months now, I am ambivalent about their usefulness.
I like the waterers:

and will continue to use them, except in winter when I'll go back to the typical containers that can sit on a heated base and keep the water from freezing. These waterers have been working GREAT all summer long. Easy to fill, easy to clean the cups, and all the chickens like them.
@Mouthpear, I've never heard of using Propylene Glycol as an additive in the chickens' water to lower the freezing point. How much to use per gallon of water? Is there any danger to using it for chickens?
But I'm not happy with the feeder totes:

They are GREAT for doing everything I wanted them to do: hold a large quantity of feed, easy for the chickens to use (hens ok, but not roosters with large combs and wattles), and weatherproof. And when I drop the plastic IBC liner over them at night, they are rodent and scavenger-proof as well:

However, the DOWNSIDE to using these totes is the MESS, STINK, and FLIES. The chickens drag the feed out of the ports, even when the bottom end of the port is an inch below the opening, and scatter it everywhere. THEN when it rains and gets the ground wet, and I drop the IBC liner over the totes at night, the ground moisture cannot evaporate - so the feed mixed into the mud just ferments into a stinky, slimy sludge. And when the sun comes up, if I don't get out there immediately to tip the liners off of the totes, then a solar heating process begins - it warms the stinky, feed-filled sludge and creates the perfect environment for FLIES to hatch.
Every day this summer when I've lifted the liners off the totes, I'm swarmed by flies and stink. So I have to move the totes every time it rains. They each hold 100-pounds of feed and breaks my back to move them. So that's counterproductive to what I intended these feeder totes to do. Besides, I have to keep the metal trough feeders out anyway so the roosters can eat. What's the point?
Unless I can design an easy system to move the totes around the pen when it rains, and a way to ventilate the IBC liners, and reduce the amount of feed waste..... then I will probably ditch this feed system. It's not worth the mess and hassle.
