Congrats! That is awesome.
We once had a goose show up and poop all over our sidewalk, but then found out it belonged to a neighbor down the lane who has a pond. I wanted to keep it, but it eventually went back to the water. I am glad it had a good home although I liked it.
Chickens are the easiest pet I've kept, however, only after we built the coop, got the safe run, etc., which was hard at first, but now caring for them pretty cool, and they give us eggs. I think I would be sure to get something sturdy at first, otherwise, if predators get in, and then it is not so easy to keep chickens.
Hope all goes well. Good luck
