Friday night around 12:00 I heard loud cacklings in my chicken's hutch. My hen sounded terrified. One chick was crying, 'till it sounded dead. In the morning, the hutch was littered with the hen's feathers, her egg smashed in her nest. The chick is gone, I presume she's dead. Saturday & Sunday that roo kept attacking the hen viciously, tearing out her head & neck feathers. No signs of a predator breaking into the hut, everything looks secure, no rips or tears in the chicken wire or the plastic covering.Sunday night, BOTH of my hens refused to return to the hutch for sleeping. I found all 5 chickens on the tailgate of our truck. The hens were seperate, at least 3' apart from roo. the roo was huddled with the two chicks. This morning, they all looked good when I opened the hutch. The hens are sticking close to each other~ far from roo. The 2 chicks are together, seperately free-ranging but still keeping a close proximity and in view of the hens. friends say Friday night's noises HAD to be caused by a predator, since the one chick is missing. Personally, I think roo was attacking the hen. AND I may have not gotten that one chick secured in the hutch B4 locking up. No body, feathers, or other signs of blood of that chick. Any opinions, from you wise & experienced chicken rangers would be appreciated.
