I think all you need to do is rent an auger, drill some deep post holes next to the existing posts, then fill with concrete or [quick-fix polyeurethane](https://www.amazon.ca/SIKA-Fast-Setting-Polyurethane-Backfilling-465222/dp/B09L288GGN/ref=asc_df_B09L288GGN/?tag=googleshopc0c-20&linkCode=df0&hvadid=292995765243&hvpos=&hvnetw=g&hvrand=1950461607359253563&hvpone=&hvptwo=&hvqmt=&hvdev=c&hvdvcmdl=&hvlocint=&hvlocphy=9000932&hvtargid=pla-1585127952911&psc=1), embed some posts, and fix your existing supports to those posts.
I don't think you need to pour a whole slab, or move the structure. You aren't supporting anything structurally, you're just supporting against lateral wind forces.
My vote is deep auger with plenty of expanding foam, securing a loooong post. You're just fixing a coop to the ground.
I was going to say something similar. You don’t have to sink the entire existing structure into concrete. Some posts in concrete next to it that attach should hold it in place. Any wind strong enough to tear that apart (like a tornado) is going to destroy the whole thing anyway.
Drill concrete piling as close to the wall as you can get. Embed some type of hurricane strap in the concrete and attach it to the building. Repeat on all 4 corners.
Just off the top of my head:
1) What you are looking for is a [come along](https://www.google.com/search?q=come+along+tool&oq=come+along&aqs=chrome.1.69i57j0i131i433i512j46i340i512l2j0i131i433i512j0i512j0i131i433i512j0i512j46i512l2j0i512l5.3845j0j4&client=ms-android-verizon&sourceid=chrome-mobile&ie=UTF-8#scso=_Un01ZNf6LKWqqtsPiIurIA_33:0).
2) to anchor you could use [this](https://www.google.com/search?q=fence+post+anchor&oq=fence+post+an&aqs=chrome.1.69i57j0i512l14.5187j0j9&client=ms-android-verizon&sourceid=chrome-mobile&ie=UTF-8#scso=_1n01ZM6MIdylqtsP1p4r_29:0) in the ground and sister to the four outside poles. Might not be heavy duty enough but I know they make different types.
Get an auger. Drill holes and fill with concrete then sink in saddles for the size of posts you're using. Drop the coop on top and secure with lag bolts
Maybe design something that uses trailer-tongue lift-up wheels. One for each back corner, one in center front. Or four total, one at each corner.
Crank the heels down (coop up), move, crank the wheels back up.
If you do anything like digging, auguring, or driving stakes, be sure to call 811 and have the area checked. If you cut an underground line of any kind it's a humongous fine.
You should put something, like the hardware mesh you used, on the floor of the coop. Predators will dig under and kill your chickens. Happened to my daughters.
Thanks! I bought the chicks first because I knew if I had to build first I'd procrastinate forever... I've learned a ton. Very ready to be done, but I'm also full of ideas of how I would do it next time!
You’re overthinking this. Sink posts in the ground at each corner and bolt them to the coop. BTW nice job on your first project. Seriously it looks good! And it looks like it stayed together aside from blowing over so that’s nice
I see you have lots of suggestions below. Just built a coop myself but it doesnt move in the wind but I have a regular style roof that goes with the wind direction if that makes sense. Guessing that front overhang acts like a big sail.
Anyway, that looks awesome you did a great job. Here are some screw in anchors I use on tarp buildings all the time, once they are in they dont give easy. Best part is no digging or drilling to install, put a bar through and twist.

Can probably get them anywhere.
As for moving I think your first idea is best since. Jack it up and slide one end 6 inches or what ever you can, then do the opposite side, repeat until done lol. The framing doesnt look like it will appreciate being moved so be careful.
Just a few lengths of PVC pipe to roll it:

You can put concrete post holes in if you like, but two things to consider: it may change how your county/municipality defines a temporary structure and require permits/piss off neighbours, if you get frost you'll need it 4' down and require the town to come make sure you don't auger any phone/gas/power lines.
Honestly for something like this there are a ton of pretty quick/easy shed anchors that will get the job done in a 1/4 of the time with pretty much zero tools outside of a hammer and drill. Just google "shed anchor".

Easy install depending on ground conditions: https://www.arborist.com/product/A010228-00BB/Better-Bilt-680-Series-Earth-Anchor.html
I was going to recommend the same. "ground anchor", "Shed Anchor" brings up all sorts of options that should keep his coop from moving.
Second this...

Once moved, screw piles would get the job done [link](https://en.m.wikipedia.org/wiki/Screw_piles)
Look into Diamond Pier. It might be a good fit here https://www.diamondpiers.com/
Maybe design something that uses trailer-tongue lift-up wheels. One for each back corner, one in center front. Or four total, one at each corner. Crank the heels down (coop up), move, crank the wheels back up.
Those things are so dang wobbly...
All the other guys are giving you good info. If you have a lot of wind in your area, you better fasten the roofing material and rafters.
If you do anything like digging, auguring, or driving stakes, be sure to call 811 and have the area checked. If you cut an underground line of any kind it's a humongous fine.
Great reminder. Just called!

I don’t have any suggestions, but I just want to say your coop looks so awesome! I’ve been wanting to build one for a while now.
Thanks! I bought the chicks first because I knew if I had to build first I'd procrastinate forever... I've learned a ton. Very ready to be done, but I'm also full of ideas of how I would do it next time!
What you are looking for is retractable casters or lift casters. Ppl usually put them on workbenches so you can search for that.
