I throw in my grass clippings into my deep litter, but I let them dry out for a day or two where they've fallen on the lawn because: 1) dried grass clippings are less likely to mat/get slimy compared to fresh clippings and 2) my chickens love eating fresh clippings a little too much, but aren't as excited about dried grass, so that helps to minimize any chance of impaction.Ahh that makes sense. Thanks for showing your deep litter! So it's definitely not good to use grass clippings then?
