I've got four girls, all different breeds. This winter, I bought straw for their house & coop, and for the dog's house. Since I had extra, I spread some next to my house & covered the area with a tarp to give them a chance to get out of the rain/snow & hang out next to the house, where their dust bath is at. Well, my poor dog has been kicked out of his house! Rather than hide in their covered & protected coop, or their large chicken house, or the protected area next to the house, just a few feet from their house, they run across the back yard, steal my dog's food, & kick him out of his house! Then they proceed to kick out all of the straw in the house. Why do they do this? I've told my dog he needs to bark at them & make them leave his house. I've gone out there in the pouring rain because the poor thing was sitting in a pile of straw outside his house to find the girls were nice & cozy inside. Of course, they have other options, so I took a stick and gently prodded them out of the house so he could get inside. Even during the summer, the birds like to hide in his house. I almost never find them in their own house unless they're sleeping or laying eggs. Birds are so weird!
