My latest batch of guinea eggs are not due to hatch for another 10 days or so.......so I was VERY surprised to see a broken egg shell out of the nest this morning! Moved the hen slightly and a chick appeared from under her - A GINGER CHICK! After I picked myself off the floor dying with laughter I grabbed the chick. I guess one of our Rhode Island Red girls popped an egg out in the guinea nest before the guinea hen started sitting 3 weeks ago! I've never hatched any chickens before as never had a broody hen.......I'm amazed!
