I admit I let my chickens (6-7 weeks) free range, and I feel very guilty about it. They mostly stay under cover and often hang around my porch. I go out periodically to check for hawks and to send out the dog, so the hawks know she's there (a big GSD). I've seen hawks checking out the chickens and at times I shoo them in their run. I get nervous when the chickens go too far from cover. I would hate to lose one - they are fast becoming pets -- in fact they've yet to spend the full night in their coop as I am too nervous about night predators. But they so enjoy cruising the yard, and scratching up all the undergrowth of every bush, and roosting in the shrubs, and eating wild strawberries and raspberries (still unripe) and honeysuckle berries and all the variety of foods they wouldn't get in a run and I just don't want to keep them penned up. They've been doing this about 3 weeks now, and so far, so good, but I know there are no guarantees. It's a hard decision, to let them live penned up but hopefully safe (predators get in runs too) or to let them live a fuller life if a riskier one. I'm still trying to decide, and watching the sky...
