Scary! I don't know, I imagine it's their age. I don't remember when mine were that young if they were very alert. Now, you can't even drop a leaf in their yard without them sounding the alarm. 

 Glad everyone is okay, though!
It's looking rainy today, so we're not doing much on the build. We just worked a bit on the fencing and got one of the doors up. Mom also built one of the remaining two doors, but it has no wire in it. We also sawed down the old gate post (because it was sunk in concrete and couldn't be pulled 

 ) and attached the old fence to the other side of where the new door is to keep the hens in before their free-range time. The place looks so different now in person!! And the girls were terribly confused about what to do at free-range time with their old gate replaced! 
Just a few pictures. You can barely tell the difference from this angle:
A little closer to the fence. I put up 1/2 inch, 19 gauge hardware cloth over the entire openings, then 2x4 inch welded wire over the bottom half and down to the ground to keep the hens from sneaking out by going underneath the deck. I was worried that it wouldn't be sturdy enough, but now that the fence is tacked down, it feels nice and strong!
And this is probably going to be a huge picture, but a bit of detail of the fence from the outside. The roll of fence behind the door is for when I get the hardware cloth up further along the wall, so I can roll it out and attach it over top. Obviously, I'll be cutting out a section for the door, but I want the lower part of it to remain under where the door is to block the girls. 
We've got to wait (again, ugh) for the next paycheck (which is a week from today) before we can buy the lumber for the roof, but at least dad's truck is fixed so we can haul it home. So I'll be spending the next week gradually getting more and more of the fence attached to the wall, or at least getting it to the corner of the deck so that we can finally take down the old fence there! 

 It keeps looking more and more like I imagined, and I'm just so excited about that!!
