Today I found one of my four Red Sex Links dead in the corner of the run. At 10 AM all came running as they always have done when I toss in a handful of scratch. At noon I tossed a handful of grapes that they enjoy. At 230 I found her dead with the feathers and skin of her lower back gone and bloody. One of the others had dried blood on her beak. They are between 24 and 30 weeks. One lays almost daily, one a few times per week and one just started today. The one who started laying today may have been the one that died. I found what looked like a bloody string or feather in the box with the egg. She was one of the larger birds, full comb with no prior indication of any problem. After I removed her, the one with the bloody beak took a few pecks on the lower back of one of the others. Could laying her first egg, an average size egg, have cause a problem (assuming it was her that laid the third egg today) she died and the other starting eating? Could the cannibal have attacked and killed her? They were both about the same size and no prior fighting episodes. Any ideas what could have happened?
