Last week I lost a hen. I was at home and I let the chickens out of the pen. When I put them away that evening one was missing. I didn't hear anything and I was outside with them most of the time. Well, today my sister let them out before I got home. When I drove up most of the chickens came to greet me but I didn't see my buff orpington or my protector roo. I started calling and looking for them and found the buff in the chicken house. Then I saw lots of feathers from the roo, but no blood or body. My sister didn't hear any type of attack. Does anyone have any idea of what might be getting my chicks? Are predator attacks worse in the spring? Thanks in advance for your help.
