Hello! Has anyone tried any of the chicken vests to protect against hawks? We have a large flock of free range chickens, several roosters, but today my daughter's pampered hen was nearly picked off by a redtail. Have had no issue for a very long time but now I'm a little concerned. We also have a few Embdon geese who roam the property and up until now I thought we were fairly safe. No lectures on the "free range" thing please, just would love to know what anyone else has tried with some success! Thanks!!
