I discovered one of my silkies in the nesting box and she looked like she was trying to do a poop Anyway, I discovered the egg was covered in blood (picture below). It broke from the thump to the bottom of the box (I was next to the box watching her). It's covered with blood on both sides. As far as I know, she has never layed an egg before. I have 3 other silkies who have each layed a few eggs in the past but have stopped due to broodiness and the cold weather (Australia, it's almost winter). Just a curious question, do all chooks lay the same size/shape eggs each time?
