Please help? I'm very worried! I went out to my chickens this morning and found half an egg shell in the run (they always lay in the nestboxes) the OUTSIDE of the shell was completely covered in bright, bright red blood! About 5 feet away was an bright red blood clot (very solid) of about 6 inches in length. There was also a pile of poop (not runny) with a small dark red clot on top. I know which hen this has come from because my girls all lay different coloured eggs and apart from a messy and slightly bloody vent, she looks fine. She is walking around, eating and drinking normally. I would be so grateful of any advice anyone can give as I am panicking!
