Oh yeah! I made sure to get the extension that goes with it. TSC is having a great sale and deals on coops and such, and I'm hoping to let the ladies free range for a while each day (SAHM/college student so I'll have plenty of time to keep an eye on them)
I hope it all works well for you. The main concern about the pre-fab coops is that the manufacturers overstate the amount of hens the coop will house. Whatever they advertise for number of hens, cut that number in half. My large 4x4x6 Barn Coop was advertised for 15 chickens and I put no more than 4 hens it. I personally figure only 4 hens in a 4x4 floor space coop - I have a run below the coop with an added run for days I can't let my girls free-range but it's still small IMO. Great that you will get more run space. Chickens get bored being penned so the free-range time they will look forward to it. What a lot of owners get concerned about with pre-fab smaller coops is the ability for strong predators like raccoons, stray dogs, coyotes, foxes, etc, can easily damage or break open a small coop that isn't enclosed in a larger sturdier fence or pen. I've read some owners of pre-fabs will use extra braces in corners/joints when assembling smaller coops to make it sturdier. Enjoy your chickens! and think safety first for them and aesthetics last.
