So many observations are made concerning hawks taking chickens in runs and free range settings. Not everyone has such problems so some of variation is a function of how runs / free range settings are confirgured or managed. I think we should look into what designs and management practices are in place to determine if there is a pattern in respect to who has losses to hawks and who does not. Might provide information that can guide cost effective methods for reducing losses. Fort Know not always required to keep birds away from hawks.
