I almost started to give you crap in my head when I first started to read your post, thinking what the hell would anyone do this for?! THEN I thought about me and my first chicks. I was so excited I wasn't paying attention to things, and then I had the lady coming with my birds and still didn't even have the coop finished! LOL. I guess it happens to a lot of us. HAHA.
It is so cool though that things worked out so very nicely. It could have been a disaster, and it worked out great and your grandkids got to witness something very cool on vacation!
Anyway, congrats on the great hatch.
