two chicken coops enough for 6 chickens?

Along with adding clutter in the run, which you’re doing, consider adding vertical stuff - branches, 2x4’s, perches off the ground. Chickens are descended from jungle (meaning tropical forest) fowl. They love going up!

Yep, I have an old fruit crate and small wood wire spool they can jump on. Plus a corner roost that’s a big favorite.

More run space will be important. If you haven't purchased the additional two chickens yet, stick with the four and see how it works, but you will need to add more ventilation to the TSC prefab (all prefabs have inadequate ventilation) in addition to adding a lot more run space and more items for them to perch on, run around, sit on.
Welcome to BYC and congratulations on joining the chicken journey.

My hubby extended the run on this tiny coop for his mom. She had 4 chickens living in it, now 3.

One important thing to think about inside the coop is how much roosting space you have. Two nest boxes for six hens isn’t a big deal, but how would 6 grown hens roost in there? I made the same mistakes in the beginning, a lot of people do! You will learn as you go. Don’t think of what you’re hearing as criticism; its advice from people with lots of experience.

I would not buy from Tractor Supply.

Instead of buying 2 TSC coops you could probably get a local handyman to build a proper coop from a used shed, or even a hoop coop for the same money. Those TSC coops make good hospital/quarantine coops for one bird, but not a whole flock. Besides, the first time you have to crawl inside one of those things to get eggs or a sick bird, you'll wish you had a walk-in coop.

Small coops with enough roost space, and with access to a big run whole day is fine as long as it’s summer. Imagine their needs in winter. And how it is for you take care for the chickens and to clean things.

The advices given are good. If you want to buy another small coop you still need a shed, a hoop coop or cover the run to give the chickens space to walk around without getting stressed during the cold months.
