Hawk took a hen 2 weeks ago, and now my hens are spending their life under my porch. They run out briefly to grab a few pecks of food but run back under the dark porch. They are free rangers and I really do not have the finances to build a pen for them at this time. Any suggestion how to get their courage back up to enjoy being out in the open? I have tried treats, but nothing doing ,they just look at me like I am crazy.
