That is so funny you'd mention garden....I started to go into a long winded discussion about my ideal winter run solution, chicken moats around gardens, but didn't have time to really phrase it well....and thought perhaps you weren't going to be interested in doing that bit of extra work......so I deleted it all
ah well, IF it's something that peaks your interest, there are several good examples here on BYC. I am leaning towards thinking of it (a chicken moat around a garden, partially covered of course, with a tarp or something solid) as just about the best secure free ranging possible in lieu of a nice big pasture (mine will get that too, but only in summer when there's no risk of flooding from the creek) and for when I have to leave on business.
On the subject of the cattle panel run like @Blooie did a detailed build of, I'm a big fan. I've thought they'd make great quail pens too.
The nice thing about parking your tractor inside the cattle panel run is they never have to relearn where everything is. Nest boxes, roosts, feed, water....all in the same familiar place.
