I have one lonely little egg, laid 6/29, put into the bator 6/30 and locked down today. For the first 10 days or so, I had water in the bottom of the bator and the vent plugs in... with no humidity gauge. Apparently that was a dreadful mistake. I bought a gauge (it was 70%) and then took out the water and vent plugs and tried to keep it as low as I could, around 40%, though sometimes got higher. Lockdown today, so I added the water back to the bottom and put the vent plugs back in. So now I wait. But, I want to know what I am facing here. Can someone please tell me honestly what happens to a chick with too high humidity? I did read that the air cell can fill with water and chick can drown when trying to take its first breath. But what else can happen? I thought I saw someone elude to disfigurement or something like that from high humidity but they didn't really say.
