ok so my chickens have a 1/2 acre fenced for them so the coyotes don't get them. Have had no issues then this morning I go out their was a killing spree last night or this morning! white feathers everywhere 5, 5 week old delaware roos gone and two of my cornish cross dead in the field. The cornish cross one was 50% eaten with small maybe 1/2 inch to inch sizes chunks off no teeth marks the one right next to it dead not touched except for its eyes.. baby roos no where to be seen except for a few of their barred feathers. no feathers or any sign of struggle in the coop all the pullets and 7 left roos are just fine happy go lucky. What was it!? Hawk, owl, raccoon? I live in SW Washington... Never had a preditor issue except domestic dogs a few years back but fixed that with the fence and hotwire and no more free ranging except for their 1/2 acre. what can I do for birds of pray? I'm not buying a 1/2 acre worth of bird netting for a roof... just have to tractor everyone??
