Planning a Chicken Coop

I went to my dad's house today, dragging along all my extra wood from other projects. We took a look at what spare lumber he had, looked at a doghouse on his property and perused my favorite coops on the internet. We settled on an adorable style from Saltbox designs. We were concerned about how well the coop would hold up in the winter, as well as the size of the run. Our run needs to be attached to the coop and extend beyond it. The Saltbox coop is around $700, but I'm hoping we can used spare wood and not break the bank here.

We took a ride to the feed store to do some more coop research, but as soon as I got in there, the red, incubator lights sucked me in and I saw all the chicks and that was it. 

The fact that I was (am) clueless about raising chickens, despite doing months of research caused me to hesitate, but not by much. I got the White Leghorns because they were so darn cute and the Orpingtons because they're, like, sooo popular (flips hair). Both types are cold hardy, which is a concern of mine because I get a lot of snow at my house. They are also good layers. 
My dad stood by, only a little concerned about my husband's reaction when I'd be bringing chicks home. 
We put the chicks in a plastic box and decided to build the coop another day. The birds will be indoors for another 10 weeks anyway, so we've got TONS of time. (Famous last words.)
