This is day 22 for my Trader Joe eggs under my broody, Penguin. So far, nothing. She is pretty mellow about me poking around so I did that just now and didn't see anything happening. I'm picking up some chicks to give her today. How long should I leave her on the eggs?

On the left is my biggest layer, a red star named Goldie who is almost 1.5 yrs old. She's been laying huge eggs that barely fit into a normal egg carton (the lid won't shut). On the right is Vanna's first egg! It was small, smooth and perfectly cute.
