This is great! Not that I wish any of this upon any one but I figure we're forewarning everyone who is going to build a coop!
CityGirlintheCountry and Heather J I totaly understood your posts! Escpecially the rocks where you are wishing you could put a post in the ground. Our fence is a bit artsy looking thanks to the flint rocks that dug under ground to live right where the posts needed to be. We have one hand dug hole for the gate post and the rest of the posts are t-posts. The hand dug hole had to be 24 inches deep. At 21 inches we hit rock.

Dh hit it with a metal bar and it broke up. I was so happy! The rock wasn't the normal flint but some kind of white rock.
Need rain? Leave your radio outside overnight. Yes it will rain!
DH took time off work to build the coop. The second day we lost power. The third day still no power to run the saws. Fourth day dh goes to the next state looking for a generator. Fifth day power comes back on! But we have to cut up the trees that have fallen and have trapped the truck in the pature so we can take the truck to get more supplies because dh believes "Ohhhhh ... we don't need that just yet." And then a few days later we need it. And he has to drive an hour to the lumber store one way, spend three hours playing touchie feely with the boards to find
just the right ones and then an hour drive home. Now he knows that knots make really pretty boards but they are hard to saw through and even harder to nail into! LOL In other words ..... if something can happen that will take your time away from coop building ........... it will!
Another thing I learned: Dark green paint looks very dark in the bucket but takes at least three coats to look that dark on light colored wood!
And the neighbor that loves to drop by and visit and says he'll be over the next day to help ..... do not count on him! The sound of a saw, hammers and people going "Ouch!", "Oops!" or "Oh no!" are the best way to keep neighbors away! It's amazing!
