I just want to say thanks for the candling tips and pictures that you'all have posted, I have a parakeet that has been sitting on eggs for a while and today I had enough confidence to candle them, out of 8 eggs all were bad, but now that I have cleaned out the bad ones she should start laying again, If it wasn't for you guys help I woould of never been able to tell they were bad until they started smelling.
