We have a female Cayuga and a male magpie born in mid March. On Friday my son found a nest with four eggs. We really don't want more ducks. She isn't sitting on them. We made pencil marks on those four. She has since laid three more eggs which we have brought inside. My question is.... Is it safe to eat those first four? We don't know exactly how long they have been there but we got two yesterday and one this morning, so I am guessing no longer than a week. Fri/Sat temps only reached low 80's. Prior to that the 90's.
