Bee, loved your pics of your babies. I think ours are about the same age 10-11 days old? I did notice that yours (CX) are much bigger and umm rounder than mine.
But on the whole I'm happy with my babies. The Delawares are definitely frailer and smaller than the other two Comets and White Rocks. I was surprised at the difference. I've lost 2 male Delawares and 1 female looks very puny. I have the AC in the store house now so they won't get so hot. All the Dels had pasty butt. I will admit that I'm so happy now. I just spent an hour playing on the seedsnow.com site and buying some more things to plant. A lot of different kinds of veggies you can't get for 99 cents.
