Thank you for all of the replies! Girls and I candled yesterday - 27 of 27 are developing!!! Used several of the tricks you all pointed out in the LG Tips link, and so far so good! Only 5 days into it, could still have quitters, but happy we are off to such a great start!!!
My daughter got a Little Giant for Christmas, and a few friends and our hens provided eggs. My daughters and I set them last night. Now to see if anything happens:)
Don't know who is more excited - the girls or me!
