Hi, I just moved my chickens to their winter location (the old dog kennel area). I'm not a fan of concrete for the run since I prefer good drainage, dirt to bathe in and plants to peck at :/ but it is also the location of a hatch which leads into the garage for their now toasty warm coop! I'll probably put something to "dust bathe" in their for them, but not feeling great about the cold concrete under them. Pros of Pine Shavings: 1. Should scoop out easily... (planning on removing old shavings to compost heap when needs it) 2. Should compost well Cons: 1. Deep litter could be costly in this 5 x 10 space 2. Might not be contained well considering the 2x2s and wire enclosure. Pros of Hay 1. ? Cons: 1. Not going to break down in compost as easily as shavings. Other ideas?
