Ok, if goats will not come out in rain to eat.....do they exit house in rain at all? I live in Portland...aka POURtland....9 months of year we have RAIN and lots of it. Yes, we get breaks but like month of Nov. and April/May....it may rain daily for weeks.
I want to make sure my goats are happy before I even get them.....I know others have goats in Portland....
I know this thread is a bit buried, but I wanted to respond here. I live in Vancouver, just across the river from Portland. We have a shelter for our two Nigerian dwarf wethers, measuring probably 10x10 feet or so. It's just a big tarp pulled over bowed cattle panels, like a hoop house. Their food and water is in there, along with a platform to sleep on. When it rains (which is a lot, as you mentioned), they just hang out in their shelter and lay around. As soon as ther is a break in the rain, even just for an hour or two, they will come out in the yard to play. Drops start falling again, they are right back inside there. It's totally doable, mine are doing just fine with this setup.
In fact, if it's just sprinkling, they will often lay up on the deck under the eaves of the house. Rain isn't their favorite, of course, but as long as they have a good shelter to hang out in, they do just fine.
