Since I lost a hen to a hawk after the leaves came down I've been keeping my flock in a 10x20 kennel cage. I've just planted grass seed in the chicken yard, and am waiting for good growth, and leaves to appear on the trees before letting them in the chicken yard again. Question is: the caged area has gotten pretty funky smelling over the winter. Should I be able to put lime down, then straw...or just DE and then straw? Will the lime hurt their feet? What do you do for keeping the funk down?
