You're definitely better off building your own coop for optimum flock health. The ventilation design in that coop was horrible anyway. If you have a gable roof you'll want both gable peak vents (and/or ridge vent) AND eave vents. Rule of thumb: 1 sq ft of ventilation per bird but no drafts in the roosting and nesting areas.
One tip I got a lot and was skeptical of was "Build it big enough that you can walk into it." Skepticism aside I built mine that way because it's not like it was much more difficult than building a low profile coop. Now that I have a walk-in coop, I can't imagine NOT having one that way
A big point of caution on wood chips: make sure they are well aged and dried before you load them into the run.

Sadly, this BYC user lost half his flock to aspergillosis by using green wood chips under warm, humid conditions, which I'm sure you have all the time. Those three factors combined can be dangerous.
I'm going to do wood chips in my run and attached "chicken garden" (500 sq ft) but it's going take a year of chip curing so I've got one more winter and mud season to manage with dried leaves and straw. Sigh...
BTW another option for both cover and feed is to try growing oats and buckwheat both (but not together in the same space) in the run and in any space that's available that you're not doing anything with. They both grow super fast, are great in poor soil, are highly nutritious and chickens LOVE them. Buckwheat is just a great ground cover, pollinator attractant, and all-around chicken snack. It won't keep at all, it's only useful green (if you harvest the grain it's very nutritous). But oats are a great snack for them green, or just gone to seed. However if you cut it and dry it, it makes a fantastic straw. Much faster, easier and cheaper than other cereals. If both are left to go to seed they will likely volunteer again; they are quite prolific.
Good luck!
