Back when I had my Jeep I belonged to an online Jeepforum, I loved to work on my jeep but I have NO mechanical ability (or tools) what-so-ever, but I wanted to learn and be able to say I did most of the work myself. I started out by wing-ing and made a lot of mistakes. Then I smartened up......I requested help from local people in the jeep community....I had a couple different "like minded" individuals show up and give me a hand with some mechanical work. I did pay them (beer seems to work better then $...they were like I am...LOVED ANYTHING Jeep), we had a great time, made some friends and learned a lot.
There are probably quite a few people on this forum, relatively local to you, who have built their own coops any may be willing to help out a fellow chicken-addict.
I don't recommend this for EVERYONE, obviously you have no idea who might be showing up at your house....BUT....if you're looking for help with carpentry skills (to gain your own), you could always try finding a local continuing ed class, or better yet....head on over to your local high school/community college and (provided they have a wood shop) talk to the shop instructor....he/she might be able to point you towards a promising student that could use a bit of $$, or even give you some tips to help you out. It never hurts to ask....
And when all else fails......YOUTUBE
