Bad news for the eggs. When I went to check them today, there was no air flow through the tumbler. The pump was running, but either the pump is starting to go bad or the air somehow shifted more to the open end of the gang valve that I was using to control the flow through the tumbler. I looked at the side of the eggs that was laying on the screen and they had fungus building up on them. I might could have saved half of the eggs, but I decided to chunk them and try again without a gang valve and also another pump. We were also gone with the Grandbabies shopping most of the evening yesterday and I didn't check the eggs when we got home last night. My bad! The tumbler works great, but I've got to control the flow through it better! :duh:
