I have a pet female Mallard duck who has been sitting on what I believe are 8 dead eggs for a couple of weeks now. She sits on them only 3-4 hours a day. She comes indoors at night and spends the daytime outside with her wild "boyfriend" who loyally waits for her return each morning. (We have another pet male Mallard who they have shunned--he has an implant so he cannot be the father.) Anyhow, I can't imagine these eggs have survived, being left in the cold overnight and unattended for a majority of the time. Should I just dispose of them? If so, how? Will that upset her? We've had her since birth last year, having rescued her from being stuck in tar. She doesn't seem to have much of the maternal instinct. Thank you!
