Well, well, well - ANOTHER North Carolinian!!  That is GRR-EATTT!!  Welcome to both you and your husband and YES, thank you BOTH for your service - because whether you were active duty or not, you still "served" right along with him through each of his schools, deployments and moves. 
I came from military background, entered military, married military, ets'd to be SAHM for our 3 daughters.  We both have friends that are still active duty &/or retired and have sons/daughters/grandchildren now entering active service.  I understand from all sides of those issues, 

  PTSD can be very difficult to deal with - I hope that, again, you are both getting the support and/or help that you may need.  Yes, gardening, chickens & some other livestock can be a great therapeutic help.  Who'd a thought "chicken TV" was a real thing (I sure didn't!!)?
I have found that I am the more outdoorsy person who does the building.  However, I am also TERRIBLE at building - nothing I do will/has ever come out square.  I can have the exact same measurements as someone else, do all the x's and math and repositioning that someone else does right next to me and still have my build not be square (same thing with a lot of baking - my mom & grandma despaired of me EVER being able to bake anything).  So, I've pretty much quit trying.  I like things I can do myself, often have to since most of the time now I'm completely by myself, and at my age of mid-50's now while not anywhere as fit or light as I was when in the Army.  I am getting very much into re-purposing, re-using and having to build from items that are already built.  I LOVE cattle panel, pallets - both the wood & plastic types, downed trees, cardboard, haystring, tires and plastic bottles.  We still have to be very careful with budgeting because we now have a larger mortgage and tons more pets and critters than ever before in our lives (though our youngest daughter did just move out on her own, again).  Our own little homestead is not anywhere close to being self-supporting yet - though I'm hoping to have much more accomplished to that end this year...
What is great is that NC is a good state to build using alternative methods and you don't have to have a completely enclosed coop.  Hardware cloth or good welded wire is a must, though, for predator protection.  Good drainage in rainy weather or flood prone areas is a must.
The biggest problem we've had with predators here in our section of Moore/Harnett & Lee counties is loose dogs (usually w/o collars & ID tags), feral cats (not our own - whom sleep with and roam around the chickens once the chicks are 3-4 months of age), a single coyote and hawks.  The months that I lose the most free-ranging birds seems to be during the winter (Dec thru Feb/Mar), during the day when I'm at work and Larry is asleep - when wild game in our area is much less prevalent.  We are currently down to no free rangers in our 7 acre pony pasture (2 - 8x8 coops have the birds in total lockdown at this time & they aren't real happy but they ARE alive - some in 1 coop are now laying eggs and the roos in the other 1 are where they need to be to be processed.  A 3rd coop is empty right now).  I will have to reposition and build some covered runs off of the coops in the pastures or do tractors.  Even using electrified poultry netting didn't work this fall and that was expensive to purchase and install (& actually difficult for me to move around - took a lot of time!).  The free rangers in our front yard have been locked up too, for now (building runs between two small coops that will have aviary netting over the top).  The backyard free rangers are down to 5 - and tonight the last 3 of the CLBs are finally being closed into their own 8x8 coop/pen.  Yes, doing runs/paddocks off of the 4 side by side coop/pens.  Those runs/pens will possibly be covered w/ aviary netting, not sure how yet we are going to do that - since the poultry netting didn't protect them from either dogs (stops ours), coyote (watched it jump over the 42" netting w/ a bird in its' jaws) or hawks (our birds did have bushes, and pallet "lean-tos" to hide under, but still lost a lot of birds). 
Breeds - again here in NC, you have a lot of options.  I've found that I have had issues with both heavy breeds during the summer and larger combed breeds during this VERY STRANGE winter this year (2018/2019).  This is actually the first year I've ever lost combs to frostbite - both in December when we had the extreme low temp/high humidity and again 2 weeks ago.  There was plenty of ventilation, no drafts and the birds were dry - yet 1 CLB cockerel and 1 RB rooster had issues with their combs.  Both hate having their combs messed with (did as chicks right up to these ages).  The larger combed Australorp cockerels did fine as did the Orpington that was out in the pasture coop/pen. 
Its hard to say what breeds do the best.  I personally feel you read over the descriptions and look at what will most fit for you, what you want and then also see how it compares to the environment and see if that helps your situation.  You can always set up fans/misters for any breed in the heat.  Almost all of our stock from 2010 to 2018 were hatchery birds - from different hatcheries - gotten thru various feed stores or flock swaps (for mature birds & even chicks once you have an established flock, you do want to be able to quarantine them).  2018 is the first year I got into breeds bred by breeders and I hope that I got some good breeding stock.  We shall see.  I'm really into the auto-sexing breeds (male & female different color/markings at hatch AND breed true) along with different colored eggs - because they are pretty to see in an open basket on our counter!
Even with "production type" birds, there might still be large variances in egg laying ability (# of eggs/weekly, age reached POL).  I am hoping that next year, some of the birds that I have that just started laying with continue to lay through the winter (they could slow down/quit over the summer since other birds that "won't" lay in winter will be laying).  I was completely caught by surprise by how much longer it took our breeder produced breeds to start laying - 9 months appears to be common for our girls - when I was used to our hatchery production birds starting to lay at 5 months and consistent at 6 months of age...  We shall see how long these breeds lay consistently as that is one thing I'm looking at/breeding for in the future.
Currently we have 55 Flowery Hens (the name of the breed) - lays large white eggs, Ameraucana - BBS & Lavender varieties - lay light blue/green eggs somewhat small, Australorps - blue in color - hatchery stock - lay med/large light brown eggs, Bielefelders - lay large light brown/pink undertone eggs, Crested Legbars - a trio of Jill Rees show line (more green than blue eggs - still very small) & a trio of production lines (much lighter blue/green eggs- still very small), Orpingtons - Lavender - pretty to look at & FRIENDLY birds but our least thrifty/thriving birds - very small compared to their size light tan eggs and a trio of Rhodebars (these aren't laying yet - should be large and nicely brown eggs).  Also have a group of barnyard bantamX that go back in lineage to our original group of 15 bantams (different breeds/type) that I was given at Christmas 2010 and the 2014 blue Ameraucana roo that survived our move to this property in 2015...  We also have a couple of other purebred pullets (considered meat birds in the countrys that they were developed in) that ended up in a mix of birds - 1 Bresse - she's laying an almost large white egg and an Altstrier - laying a smallish cream colored egg. 
My plan with this many birds?  We have 5 dogs currently and 6 cats (starting to feed them our own produced food instead of purchased dry kibble), Larry & I & our 2 adult daughters, 2 SILs w/ 5 grandchildren between them, 1 adult daughter & her fiance  that we provide most of the chicken & eggs for (getting there).  Though these aren't "meat birds" per say - they are tractored/free ranged and the cockerels are processed, some of the hens are processed and we eat/use a LOT of eggs.  Love our fowl proteins!!  I've learned to make bone broth this winter and we put feathers, skin & bones into compost.  We haven't raised/processed actual cornishX meat birds, but not really sure we need to with the selection we've got, LOL.  2019 will be our first year processing a larger number of birds and we figure we need to do around 150 just for my husband & I w/ the cats/dogs.  Got my first batch of eggs in the incubator (learning that, too) and we will see how many actually hatch from the 36 pullet eggs we set. 
So - welcome to BYC.  Hope you enjoy all your visiting as you learn and try out different ideas with your chickens.  If you ever need any ?s answered, simply ask here in the forums.
