When I can, I let the hens out to free range. Soon it will be dark too early for me to do that. Can I put some hay in there? I put coastal hay in the boxes and they strewed it all around and I assume ate it! It is mostly gone. Do they need that stuff? Will it hurt them? I have a good T&A hay avail should I share it with the girls? I wondered if it would get caught up in the crop?+
