Great site and great information. I have just obtained some chinese and jumbo ringneck pheasants and now that they are laying I have been trying to candle the eggs but having great difficulty seeing anything. I wonder if I am using a strong enough light bulb? I have taken a scotch container, cut a hole in one end for the egg and the other I have it set into a small light fixture with a 100 watt fluorescent bulb. I still cannot see through most of the eggs. I have been able to see the air sac and that is about it, they are too dark? Any suggestions out there, do I need a certain type of light bulb? I have set 42 eggs so far and they have been in the incubator for 15 days so far, none of them stink yet so I am thinking that is a good thing! LOL but really want to be able to candle them successfully to determine the viability of the egg. Any advice, suggestions would be most welcome. Thanks in advance.
