The zoo trip would definitely be worth it. Ahh, I feel your pain. Ours are also pushing 7 weeks! I was really hoping they'd get in today, but at this point, it may be tomorrow. Idk. I'm feeling anxious. We dealt with a solid week or more of rain prior to this week. Thank God it has cleared up and is now beautiful. Maybe your forecast will change...
Your coop is adorable! I am kind of embarrassed to post pics of mine after seeing such as yours. Mine is ugly. lol It will be cute in time, but as of now, it's got a ways to go. I really want to use the same siding you used. The T1-11. But it is expensive!! So we opted for OSB for now. And are planning on covering it as our budget allows. And it looks like your husband really knows his way around carpentry. My bf is no master carpenter... lol But I know the chickies will be happy, regardless of what it looks like.
Haha, he really doesn't!!! My dad is a carpenter and he didn't have sons so I went with him to jobsites and learned a lot. I used to work with him in his shop growing up. When all the other 6th graders made solar cookers with pizza boxes and tin foil, I built a greenhouse style color cooker with hinged lids and a thermometer and other fancy features. And it wasn't just my dad building it for me. I had to design what I wanted and then he would showme how to make it and assist where power tools were necessary.
I designed the coop, drew it out to scale on graph paper, including the framing. I instructed him on how to do the things necessary to construct it. Fortunately, the husband is smart so he remembers things after doing them once. And he is full of ways to improvise in a pinch. And he really can come up with ways to save time that I wouldn't have thought of sometimes. I've got the book smarts but he is much better at putting it into play. We make a good team that way.
Hope the OSB works OK for you. Prime and paint the heck out of it. It's basically just sawdust and glue. If any moisture gets in it, it will deteriorate ten times faster than most other options. Its better used for interior projects where an outer shell made from some other material protects it from the elements.
Mine looks good but it hasn't been cheap so take some solace in that haha.
