Maybe revisit the hoop coop idea. These are easy, low materials, affordable. Even if you started with one panel they'd have quadruple the space of a doll house style prefab plus actually safe.
Read and consider the reviews. Also do you have a tape measure? You need toi get one if you don't so you can see and lay out those dimensions.
The run is 23.5 inches high. That's less than 2 feet. Knee high.
ETA so that makes the actual coop just 11 inches high. A sheet of paper is 11 inches...
It matters because dogs can see smell and hear them much better than we can. You have large predatory snakes there that can literally feel them in the air.
It would seem you need either much more money plus help(pre fabs won't be delivered assembled) or a little money and ingenuity plus help. Either way you'll need tools. And either way you'll need it soon, they aren't safe outside even one night right now.
Time to do some soul searching. Do you...
Craigslist concerns are easy to address. When I want to meet someone alone I make them meet me at the police station parking lot. If they won't, then I don't need it.
That run from wish may be very flimsy. Could be flimsy enough for a stray dog to crush. No way to tell except buy, wait a month, then be stuck. Any dog house they sell will be weak wood junk.
Get the dog crates imo, meant to keep one in will keep one out. You could get 2, connect them, add...

Get both of these plus hardware cloth and zip ties, find bricks etc, plywood or roofing panels. And you'll be set without any real building. Search here for predator proofing for ideas on the details.

And a roll of hardware cloth, not chicken wire, and you'll have safe place to start on a run. Then find another to be the coop.
Just use the cage you have outside in the house once they have a coop. Save your money for the coop.
You can't make a chicken wire and string structure safer. Get a big dog crate and cover it with hardware cloth and plywood you can have cut to fit at Lowe's home depot etc. Set it up on...
Well as I said if you have 150 to work with you could pay him for fuel and time to help you. Shop Craigslist every day for new items that could work. Search these terms,
Dog kennel, chicken coop, cage, wire fence. I even saw big bird cages that laid on their side(chickens don't need the...
Yes I agree that's not ideal. I thought the free one sounded better. What's your take on that one?
Tell me what you do have for transportation. Does your mom have a car, SUV, etc.
Is there a family friend with a truck? Do you have a grampa or aunt with tools?
You are in a position to...
True about the run.
When you shop on Craigslist people usually take an offer a bit below what they are asking. So if asking 200 they may take 150.
Edit to add, for more ventilation you knock out boards and cover with hardware cloth.
What's your transportation situation?
