I can only let my 3 hens out for about 30 min each day. They look so thrilled when I let them out that I'm feeling guilty about keeping them in all day. But I'd feel worse if a neighborhood raccoon (there are lots) or the neighbor dog got them. Or if they devoured my whole veggie garden with all my winter seedlings. The run is about 22 square feet. Of course, they have food and water. I throw some treats in every morning. Are they fine? Am I ridiculous to worry about this? Someone reassure me!
