Our 6 hens often free-range in out larger, urban, fenced backyard. Today, I heard complete mayhem from the hens, only to witness what appeared to be a hawk swooping through the yard. I ran out and scared if off our fence, and didn't lose any hens. (The main target, however, appeared quite distressed; when I put her back in the coop with the others, she sat still in the corner, with her head completely bent forward. They are all acting fine now.) I do not have a separate, larger run that I can cover. Plus, that is just not realistic for our space. I obviously can't cover the entire yard with netting. Any other ideas to protect them, other than only letting them out when I am outside? I assume this hawk will return, now that he knows there are hens around, right? Will this hawk be a year-round problem for me?
