Hello! I have just completed my 3rd hatch, which I seem to have the same problem(chicks dieing in there shell). I have been reading day and night on the issue and think I have a resolution, however I would like to ask a question before starting round 4. Every where I look ppl are talking about putting water in the incubator, even the instructions say so, however I read that the humidity should be around 45-55%. 'Comfortable' humidity levels for human living is 65%. Sooooo if you have a forced are incubator then you would need a 'DEhumidifier' and should never need to ADD water, right? Basically I can't keep the humidity under 55% without any water and I believe my chicks are drowning after puncturing there air sack. Help would greatly be appreciated. Thanks!!
