I have incubated and hatched ducks, muscovy ducks and guineas...... my daughter in law had given me some chicken eggs to incubate for her... these eggs are very dark shelled...unable to candle/can't see thru shell... is there any way to tell if the eggs are good without candling or do I just need to wait for due date?? since I have incubated and had successful hatch rates I thought chicken eggs wouldn't be a problem....but I was wrong...can't tell whats going on... guinea eggs were hard to candle but these darker shelled chicken eggs are somthing else..... anyone??
Are you talking dark brown or just normal brown or blue or?? I don't think you can candle the really dark brown eggs. If they have really gone bad they will float. If medium color you may just need a brighter light or darker room. When all else fails, patience is a virtue.
I used HIGH INTENSITY 150 LUMEN LED light from Costco and it work just fine for Black & Splash Copper Marans eggs. You can buy a package of 3 for under $20.
