Duck egg discolouration day 27

[Beachchickenss]

Hello! It’s day 27 for my duck egg in the incubator. We found it in the garden abandoned by its mum. I’ve been candling at the right times and have seen good progress. We went into lockdown on day 25 and since then nothing has happened apart from dark patches at each end. The dark rounded (not pointed) end does have what looks like a small nick in the shell which has been there since the start but doesn’t go all the way through so I left it. It looks like a weird brown colour on the inside but hard to tell. It’s worth noting too that the egg did roll slightly during lockdown when I knocked the incubator but I repositioned it.
The pics have a bit of a weird look as I took them through the plastic of the incubator but hopefully you can see the darker colour on each end.

Any tips? Should I just wait and see? Should I candle it for signs of life?
Thanks x

Update on the small nick - I’ve put some coconut oil on it as it keeps darkening

Candle it in a dark room and see if you see any movement in it.

Just had a look and don’t think I can see anything moving. It’s so dark though. I can still see a decent few veins and the air sack but it doesn’t look like it’s been internally pipped. Can’t hear anything inside the egg either. I’m so sad if it has died! How long should I leave it?

How does it smell? And is any fluid leaking from that nick?

No smell, no fluid

No progress so far. I’m going to candle again this evening and see if we have an internal pip.
