I have a Mandarin hen that has been on a next for a LONG time. I know it's been longer than 28 days because I have call duck eggs that I collected about a week after she went broody and they are pipping as I type this. She has the eggs buried under shavings and some feathers. She only comes out about 2X a day to eat. Could she be sitting on non-fertile eggs? I'm scared to move any of the shavings and candle the eggs for fear of her abandoning the nest. She is 2yrs old, but this is her first time sitting. Can anyone advise me as to what I should do? Should I give her more time? Will she abandon the nest if I move the shavings to candle the eggs? Thanks!
