I have 9 RIR about 22 wks old. I am tossing around the idea of letting them free range when I am home (weekends). I am concerned that something may happen to them if I let them out. I have about six dollars each in them, and I don't want to lose any of them. I live in a rural area, with a large woods(38 acres) right behind my property. I know that it is better for them to free range, but.... you know. Please give me some advise as what is the best thing to do.
