I also only free range when I'm home and can supervise. We have too many hawks so when I hear the crows going nuts I run out to lock up the birds. They're almost always already in the run (but that wouldn't stop a hawK) so I close them up. I had 19 birds in a 10 x 20 run but I felt it was too crowded. I sold some birds and now have a dozen in there. It's easier to clean & gives them more space. If they don't get out for the day I usually try to provide an unexpected treat for them....except I think it's expected because they're always rushing me at the door!
I think I my chickens have the good life.
