Hello, My Maple finally went broody, she is a partridge silkie. I have her sitting on 2 duck eggs (that were added today) and 3 silkie eggs that are not fertile (no rooster). Can I add more duck eggs? Will she notice the difference and only sit for the 21 days or will she wait til they hatch? I have never had a broody hen before and I just wanted to make sure she will last the duration for the duck eggs... Thanks
