Ok, so far this Fall we have had: Batch #1: Our leghorn mutts eggs & Hinkjc's Buffs - 70% hatch rate Batch #2: More of our Leghorn mutts - 80% hatch rate Anyone want some Leghorns?? Batch #3: 2 Ebay purchases - 10 Campines & 12 Mutt mixes - 35% hatch rate & 2 CAMPINE EGGS BLEW UP IN MY FACE WHEN I DID THE FINAL CHECK!!! One was really bad. It blew up all over me when I opened the top. It smelled like a sulfer pit and even the dogs were gagging. I never knew this could happen. OH IT WAS NASTY!!! This only happened with 2 Campine eggs. The second egg wasn't bad because I covered it. I have two more batches at day 14. Batch #4 is 24 Delawares bought on Ebay. Batch #5 is 30 of Hinkjc's & Speckledhens eggs. Now I'm getting nervous. Temps are steady around 100. Humidity is 40-50 and then 60-70 after day 18.
