On day 25 please help

[Ercwyne]

I have 31 eggs in the incubator and none of them have hatched. Currently on day 25. This is my first time incubating.
I checked the temp of the incubator early in the process to check that it was accurate.
I increased the humidity to 65-70% for lockdown.
I was waiting, waiting, nothing so I decided to candle a couple eggs quickly last night and theres visible air sacs. One of the eggs started wobbling while i was trying to candle so theyre still alive.
I'm wondering if the forced air is no good and making them cool down? What should I do? Im so anxious I really want this hatch!
Theyre pekin and pekin silkie cross.

Where did you get your eggs?

Where did you get your eggs?

From my own chickens. Father is a pekin. Mothers are 1 pekin and 2 silkies. We no longer own the rooster because we had to get rid of him due to council laws, so this is the only chance ive got with my own chickens.

Pekins need human intervention .The feathers on both need trimmed to assure fertility of the eggs

Did you candle the eggs during incubation?

Can u take pictures of some of the eggs while candling them? I found a post of someone who had a similar situation. There might be some helpful information.

I read that one ealrier and its giving me some hope that they may still have a chance.
Im not comfortable opening it up and candling at this stage coz im afraid it'll do more harm than good. If nothing happens by tomorrow afternoon i will open it up and take some photos.

As in they need intervention to hatch?? Or that they need trimming to mate? The eggs are fertile otherwise they wouldnt have developed at all.
