We have 8 hens who free range in our backyard. It's only 1/4 acre property with shrubs along all fence lines and several trees. One of our RIRs disappeared last week for a couple of days. We thought maybe an assault by air had taken place due to the lack of any feathers or other signs of a struggle. Then, she just shows up yesterday, eats some treats, lays an enormous egg and now she's gone again. We have looked EVERYWHERE for her several times. Any ideas of where she could be going and why she seems to be hiding out?
