I am trying to find out what to put in our nesting boxes. I have them closed off right now because my girls are only 10 wks old. We are using the deep litter method in the coop but am wondering what to use here. Do I use hay? Straw? What is the difference? Saw some alfalfa hay at the Tractor Store- is that what I want? Clueless here so please be specific about what you use- thanks! Only have 4 nesting boxes, and 3 girls right now- getting 4 more chicks this spring. Love some advice. Thanks everyone!
