This looks like lots of fun! I never heard of a Hatch-a-Long before. I have two incubators full. 11 due to hatch next weekend, and a bunch more in about 2-3 weeks. Hatching silkies and rocks on Saturday. Trying to hatch some Ameraucanas in the next hatch, but the 2 hens are hiding from the rooster, so haven't had any fertile ones yet. They are afraid of the other hens. The 2nd hatch will also have some silkies, some rocks, and some extra eggs that are a barnyard mix (mostly Easter eggers.) I'm also hatching a bunch out with my first-graders! I just have to share the excitement! How fun!
