Day 23 no progress, but visible veins in membrane?

[Cryvidae]

What’s the latest you’ve had an egg hatch? I‘ve been intently watching a silkie egg of mine at the end of day 23, and figuring it was silent and not moving meant it was dead, I took it out to candle and there’s still visible veins in the membrane, and to all intents and purposes it looks like a day 19 egg! I float candled it, and though I couldn’t see movement it floated with only the very smallest amount of the top out of the water.

After much confusion, I took out my reliable reptile temperature gun to check my two independent thermometers in the incubator, and the incubator is running a degree and a half too low! It’s the only silkie egg that made it to lockdown amongst my other breed and I was really looking forward to the chick.

So to all who’ve hatched here, is this egg possibly still viable, and how late have your eventually successful hatches been?

When I first got my incubator my second thermometer was incorrect so mine ran low I had a bad hatch rate only 4 out of 12 chickens a mix of Wyandotte and is a browns
The first hatched 3 day late and the last 5 days
I would just hang in there and hope

I still have a glimmer of hope, just don’t want it compromising the other eggs due next week! Sitting on your hands during hatching period seems the worst part of this process

Well some people are against it due to risk but if there are no crack pips or chips you can float in incubator temp water to see for movement
it can drown alive chicks if water gets inside
Do more reasearch as I never knew I could do it and haven’t done
I will also try and find an amazing guide to assisting hatches that I read on here yesterday
Again a lot of people dis agree say that it just weak chicks and that assisting is not natural but incubators are not natural neat are auto turner yet we use them
A lot of the time when a chick can’t hatch it is due to a slightly wrong condition whether the was a time spike or dip or humidity was out by a mear 5%
sorry for bad English I’m disgraphic

For assisting read this it’s long but worth it

Give it some more time and keep candling every day to check for movement. Not moving is generally not a good sign though, even if it has veins (fully formed late term veins take longer to dissolve than first week veins).

I made a small hole today and immediately it became very obvious the chick inside had not made it. It was positioned with its head under its legs and unable to pip, and had never even finished absorbing the yolk. RIP, little one.
