I would recommend lowering the humidity in keeping it closer to 35% throughout instead of 50.... Then I would recommend not raising the humidity until you see an external pic and then only raising it to about 60.Lowering or raising? These eggs were shipped and the air cells were wonky from the start even though they were beautifully packaged. I kept the humidity around 50% the entire time although it did drop a couple of times into the 30s while I was working. I don't think it was low for more than an hour or so each time. When I put it into lockdown, the humdity levels were between 65-70%.
I thought you were supposed to raise the humidity to keep eggs from getting shrink wrapped? I'm asking because I had a hatch at Easter where a chick died from getting shrink wrapped. I was trying to be so careful that it didn't happen again. Now I'm wondering if I really just don't understand what causes shrink wrap?
