Where did you get your chickens from? How do you plan to continue to care for them? They require proper feed and sometimes medical attention.
The cardboard house is cute, but it won't hold up outdoors.
The run you are looking at is ok, but again, it is not a shelter. The reviews on Amazon say that it rusts fairly easy. There is another one listed on amazon with a peaked instead of flat top. It has similar reviews. If you can buy stuff like that, why can't you buy a dog house (which would be better protection than what you currently have)?
Also, Wish looks like an app of sorts, so we can't see the whole thing wothout logging on.
Is your budget $150 or $200? Were you able to check on the free coop listed on craigslist? Maybe try to earn some more money to increase your budget. Teens can get some good jobs like babysitting, mowing lawns, etc...to help pad the budget.
