Hi everyone! I currently have 10 Toulouse geese eggs in the incubator (this is my first time with geese) and have been candling regularly to check their progress. All eggs seem to be developing really well and have their eggs sacks but tonight I noticed I couldn't see the air sac in one of the eggs... when I put the torch to the egg, it was completely black???? They're getting to point of hatch. Have I lost this egg or is this normal so close to pipping???? Thanks so much!!!
