I am new to the whole chicken game, but am enjoying every minute of it. I am wondering about periodically allowing my birds to free range. By periodically I mean a few hours at a time. My biggest question is how hard will it be to get them to return to the run/coop when I want them to. I assume they will naturally want to roost in the coop at night and will return for that themselves. Id like them to have some time to really stretch their legs and clean up on some bugs and pests in the process around the yard Thanks in advance!!!!
