I have a 20 wk old Leghorn who will lay soon hopefully. They don't have acess to the big girl coop, I have to carry them there each night, so I decided I needed something for a nesting box...well, I put in a tupperware container filled with straw...instantly her two 10 week old 'babies' hopped in and scratched all the straw out. So I put in a large kitty litter box filled with straw! They all love it! They treat it like a mini-coop. They love to shelter against the wind and cold in there. They're so sweet!
