I just had 8 new chicks, and cleaned the bator, and set 14 more eggs in it. I forgot to put the little round vent plugs back in, and the eggs were in for 1.5 days already. Humidity is between 50 and 60 percent, temp is 99. 1. I just put one plug back in, is this okay to have been out that long? 2. Should I have had BOTH plugs in? 3. Will the addition of the plug raise the temp and humidity? I won't be home until this afternoon, and hope it doesn't all come undone while I am gone. Thanks in advance!
