Chickens do nest but they are not gathers like birds that fly. And when I suggested about throwing some of my scraps out for birds I was told it was not a good thing to do by Rangers in Yosemite. Can't remember the exact reason but was told not to do it, so I don't anymore. I agree with Zozee, use it to make other smaller items. A friend of mine took my left over batting for purses.
