I have four pullets, all about three months old or a bit more.  They are in a chicken tractor that we move around the yard.  We've gotten a kennel for the dogs, so now we can let the chickens out some to free range.  Any suggestions on how to handle it?  How do I know they won't just all run off?  I assume they'll come back in when it gets to go-to-your-nest-box time?
