One of our girls is sitting on 6 eggs! One has hatched and is doing well. We have a second that looked like it had piped. However, we took a flashlight and looked in and the chick hasn't even broken through the membrane to the air sack. Our concern now is the membrane will dry out and the chick will not be able to break through. Not sure how the shell broke open to begin with. We dampened a napkin and placed it over the hole for moisture. Chick is/was moving and alive. We placed the egg back under Mom. Any ideas on keeping the membrane moist? Thank you!
