I have 12 hens ( a real variety) and a new Buff rooster who we just adopted and he is about 6 months old.
Started finding the pictured object in a nest box about a week ago. Don't know what it is, but am finding this 2 inch object about every other day. All hens are eating and drinking well. No sign of stress or disease. They free range within a 1/2 acre fenced pasture. What is going on?
