Nice!!! Looks like your ladies will be very cozy. And a great idea to put the front fence on hinges! If you have enough goats, it really isn't doable anymore to pitchfork all the pens I have a high barn like yours, too with lots of 'vertical space' as you put it, but I like that, because it is so much easier to ventilate than when you build roofs/hayloft over the stalls like you see in horse barns. That does keep the stalls warmer, but in my experience keeping the barn aired out and dry is much more important for goats than keeping it warm. My barn has doors open all year long (I do temporary close doors on wind side if the wind is very harsh or if it brings rain into the barn) and waterbuckets do freeze in the winter, but the goats are all in large pens with dry bedding and mostly out of the wind and then they really don't care if it freezes. I am careful with post dip when it's very cold. I put it on in my parlor (where I do have a salamander heater to keep equipment/waterlines freeze-free), leave it in for a minute and then dry it off with a clean paper towel. I know that's a compromise, but I don't want to risk frozen teats and this has been working well.
Enjoy your barn! Looks like you still have plent of room for expansion, by the way

Oh, and the boards along the bottoms were done to keep the bedding from spilling out so bad, between the boards and the tiny squares of the hog panels. The tiny mini babies should be contained. Last year I had trouble keeping my kids in their pens.
