You’re saying it’s unlikely they’ll hatch?
yes it doesn’t look like a hatch in this clutch. they are way beyond the normal 35-38 days of incubation although the parents are still incubating. perhaps the eggs will break, disintegrate or parents will start to leave nest more and more as nature sends them the message. they are devoted to each other so i wonder if another egg or two might not be possible - if their hormones are still up. last year they hatched 2 eggs - but lost one chick to hypothermia due to weather.
