transitional housing for 2 week old chicks

[redinator]

I have 5, 2 week old chicks that need to be transitioned outdoors. I plan to build a large enclosure with a coop in it, but they are still too small for anything I can find online. The biggest problem is the weather isn't cooperating. I wouldn't be comfortable leaving them out at night until night time temperatures stay above 60 F, or they are fully feathered. I need something temporary and inexpensive where I can bring them out a few hours a day and slowly progress to leaving them out at night.
