I actually like the second one better. It seems more simple, so there's less fuss. I like to remove my feeders for cleaning. Plus, every time I add more chickens, I can add another feeder lol. It's difficult to choose coops online. It took me months to choose a plan and we still made changes as we went. The best advice I got was to pick something that would be easy to clean.
I plan on making a PVC gravity feeder similar to the one urban coop shows. With only 6 birds, it should be fine. I'm also going to get a chicken fountain nipple waterer system so they have a constant supply of water. The 2nd one seems like a lot more real estate to me, for less $$. With quality water sealing, it should last quite a while.
I love the PVC feeders. My favorite too. I also use the nipple watering system with a five gallon bucket. Hoping to make it automatic this year. I ordered the float thingy, just have to hook it up.
