I'm currently using bails of straw as bedding in my coop and nesting boxes. It's comming time to get more, but I've been considering some other free options. Perhaps renting a wood chipper and using those chips in the coop. Or what about ferns, my yard seams to be overrun with them I could cut down quite a few and dry em for a few days? I'm wondering what's really the best? or if I should just stick to the straw? Thanks in Advance.
