IM GETTING CHICKENS!!!

e My friend got chicks this spring, and has decided to move from her trailer house in the country to a 5th wheel in town at an RV park, so I get her chickens!!! Problem is, I dont know where to put them, my yard is not very big and very square. I have 1 pear tree off to the side, and a "berrybox" with blueberries and strawberries in it. I was planning on 3 small chickens but it looks like chicken math happened without me and i get 6-8 large chickens that are just starting to lay. She has a coop built that she will bring down to me as well that is square(think porta potty size), I need to build a run, Hubby wont allow them to free range very much.
What do I do??? Im so overwhelmed, I havent spoken to my landlord yet about the number of chickens allowed, he approved chickens when I asked him about it a few months ago. I might end up getting some butchered before winter hits. My Hubby is going to kill me in my sleep because of the chickens and we are getting 3 hedgehogs from a different friend soon as well. To top it off we have no timeframe for when they are coming down, she just decided to move and give them to me. I only have a 4 foot fence, a racoon that is trying to eat my bunny when I leave her in the cage to eat the grass instead of her hutch, and alot of stray cats that go into my yard. And I dont even have a backdoor to get to my backyard, my dog tries to eat the bunny so I can only imagine what is going to run through her head for chickens. Im going to find a paperbag, this was supposed to wait until later not all get dropped on me now, but at least car shows are over for the year(I hope).
