I went and checked on my hens and roo today and one of our RIRs was laying outside in the run dead. She had no signs of being attacked (no blood or markings of any kind) then when I picked her up she was bloody on her lady parts. Our chickens are about 19 weeks old and just started laying last week. We are not sure which ones are laying, though. Could she have been trying to lay an egg and died from it? Could the roo have been too rough with her? Has this happened to anyone else?
