So my hens were able to scratch around in the dirt yesterday for an hour or so while I cleaned their coop. I threw apple, kale and bread and in their pen and said "have fun". When it was time to put them away I noticed that they weren't so much pecking as eating dead dried grass (which came out easily) and dirt! This morning there were lots of blackish droppings. They seemed hungry and demanding, just like every morning----thank goodness. Should I stop letting them do this? I was hoping to let them out again today after work, they have cabin fever! But, I am worried about impacted crops from the grass, spindly and pathetic as it is. Thanks in advance.
