Okay so on the 22nd we noticed our Khaki Campbell had laid a nest of eggs-not sure how long they have been there.. she didn’t sit on them constantly until about 3 days ago. I candle every couple of days and right now I’m not seeing veining. Should i be seeing veins at this point or still too early? When i candle there seems to be something in them- more than just the yolk. She has been with our male Pekin.
