I have a hawk watching my chickens. It swooped down at them yesterday with us outside with them! I've heard music will keep them away. Is there any thing to this? Any ideas to help would be appreciated. We have them in a partially covered area now. We really hate to make their enclosure any smaller, but don't want to lose anymore chickens. We lost one two weeks ago. I have also heard that once the chickens are full grown, they will be safe from Hawks. Is that true or are they just as vulnerable?
