My DH and I built a hoop coop last weekend. Sharing pictures from the build for those who might want to do something similar..

Specifications and requirements -

Inside Sq footage - 6 ft x 8 ft
Poop boards
Adjustable ventilation
Automatic chicken door

Here's final product (inside and front) :

I started this project by painting and/or watersealing all the wood FIRST. That took me a couple of days.

Next, I laid out the bottom frame in the general area. I used 2x6x8s for the bottom frame. I doubled up the 2x6s along the front and back which will support the end cap walls. Because I wanted my inner dimensions to be 6 ft x 8 ft, this meant I didn't need to cut any of boards and I could utilize the extra space on the front and back end caps to create an overhang.

Next we laid down our cattle panels side by side. Cattle panels are 16 ft x 50 in. Which means they will have a 4" overlap in the center if you want to attach them to an 8 ft long board. To make this easier, we used zip ties to hold the overlapping pieces together and give both panels some stability so you can handle it as one piece instead of 2 separate pieces. Once it was zip-tied, we used conduit straps to attach the cattle panels to one length of the 2x6x8 side wall. Once this is attached along one side, it will be very easy to push the cattle panels up in the center and adhere the remaining side with conduit straps.

We used this chart to estimate a center height for our hoop coop. You'll need this height for planning out your end cap walls.

Beginning to build the front end back end cap walls. We built in "horizontal" supports into our wall frame to provide a place to nail in and secure the poop boards.

Once the poop boards were installed, we started to cover the frame. We used 4x8 (painted) particle board sheets. To help line up the bottom correctly, we sandwiched (2) 2x4x8s together and laid at the end edges between the 2x6 walls (the sides that the cattle panels are attached to). We used these 2x4s to support the weight of the 4x8 sheet while it is held along the length of the end cap. This allows you to use a marker and trace where the cattle panel touches the 4x8 sheet. This traces helps you identify the arc you need to cut in the panel to make it fit perfectly. After your sheet is cut, simply push the 2x4 supports against the end cap wall and use it to support your sheet while you trace out any openings such as the door, window, etc. We followed this process for the front and back end cap walls.

Next we wrapped the cattle panels with hardware cloth. We used zip ties (again) to generally secure the hardcloth in place. Next week used chicken wire as an apron around the bottom along the ground to discourage predators from digging. We slipped the apron wire underneath the hardware cloth and then secured BOTH together with screws and washers. Along the end cap sides, we used cut the hardware cloth, folded it over to the outside frame and secured it with staples.

Afterwards, we pulled a heavy duty tarp over the hoop coop. Since it was bigger than we needed, we carefully folded the excess underneath so it wouldn't stick out. On the west side where rain & wind predominantly approach, we secured the tarp to the frame with washers & screws through the metal grommets on the tarp.

We used polyester rope at 18" intervals over the top of the hoop to secure the tarp in place. One the 2nd side, we slightly drilled in the screws & washers but left enough room to allow us to loop the rope and tighten it down before then tightening down the screws & washers the rest of the way. Here's the result.

We had severe storms just a few days later. The tarp never budged and the coop stayed warm & dry. In the summer when we get triple digits and high humidity, I can easily roll up one or both sides of the tarp to allow a breeze/cross-breeze. This capability was one of the most important reasons why I went with this type of design.
 
Looks good!

A nice illustration of how easy this style is to build.

If you find the humidity building up or it getting too hot with the sun on the black tarp you could easily add some top-hinged windows to the wooden end on the leeward side to give more airflow.
The tarp is silver on one side and black on the other. I opted for the black side up to help pull heat into the coop during winter. In the summer, I will probably flip it over to help reflect the sun. This area is also very well protected by large oak trees which shade afternoon sun in the summer. The trees help but I'm really excited about the ability to roll the tarp up to give them an easy cross-breeze.
 
"I" would just use a second tarp silver side up and cut windows into the wooden ends.
I didn't want to add windows. There is already built-in ventilation along the top 6 inches on both ends where I used hardware cloth around the beam support. You can see it here -

However I wanted the black side of the tarp facing up during the winter to help absorb heat and warm the coop naturally. I will use the silver side in summer to reflect the sun during the morning hours (sun is blocked by trees/shade in afternoon and evening during summer). I will roll up one or both sides of the tarp to create added ventilation during summer because it gets sooooooo hot here.
 
Chickens need air movement & exchange (circulation & ventilation) as well as shelter from the wind ,rain and snow. Providing one and not the other can be deadly.That black tarps going to absorb heat and cause them to overheat on sunny days.Set a temperature gauge on the wall and get an app that sends notifications to your phone so you'll know how high it goes.

You might get by with less ventilation in the winter than summer but the typical coop needs 1 sq foot per chicken if this helps.
