I currently have a 10x40 run for 34 chickens. Occasionally, I like to let them out of the run for only about 1/2 hr at a time due to our predators. We have lots of coyotes/hawk etc. I usually only do this if I am working in the garden, or am close by. couple questions: 1) is this even worth it? I thought they would like the change of scenery/ more bugs etc. but is 1/2 hr enough time? 2) can I still consider them free range when I eventually sell their eggs? they aren't laying yet, but I'm sure they are close. I also like giving them treats/scraps/etc. so they do get a variety in their diet.
