New to this. Are my duck eggs fertile

[New duck mommy 2021]

Hi guys.
I have been doing as much research as I can but still struggling.
I’m not sure if my eggs are fertile
I have tried to incubate 10 now and after 8-10 days have had no growth and have taken them out.
this is my girls second clutch of eggs they have been in 3 days but I removed the small one as I read to small of an egg can have issues later on. I decided to check it
Here are a few pictures from it

If anyone can help I would be very also when I moved the yoke around it looked darker blood or orange colour. Not sure if it was a baby starting or the egg cooking over time being in incubator. I didn’t take pics of that part tho

Unfortunately after an egg has been in the incubator, the blastodisc/derm starts to break down, so there's no way to look at a cracked open egg after it has been incubated for any period of time and tell if it was fertile.

If you want to crack open a fresh one and post a picture, that would work

What is your ratio of male ducks to female ducks? If you have too many females, it can be hard for a male to keep them all fertilized.

But to address other possible issues aside from fertility, can you tell us what your incubation technique has been like? Such as what temperature you are using, whether the incubator is still air or forced air, what humidity you've been keeping the incubator at, and what your egg turning schedule is like? How old are the eggs when you start incubation?

Thank you for the reply
I have 2 female Pekin ducks and 1 male khaki Campbell. I have seen him mate both girls over the past 3 weeks a lot lol. The girls were born start of may and he was born start of July.
I have my incubator set at 37.5 and humidity is 45-55
Those eggs were only 3 days after being laid
I gather each morning and keep them pointy end down in a bowl room temperature
I do have 6 more eggs i have gathered over the last 3 days that have not been in the incubator I could try one of them and take a picture now for you

I forgot to add it’s forced air and I have been turning them 4 times a day

That one does look fertile!

So that raises the question of why they aren't developing. I would double check the incubator with a thermometer that you've calibrated and know is accurate, to be sure that the temperature in the incubator is actually what it says it is.

That’s what I was beginning to wonder. I bought it off amazon So Today I went and bought one from peavy mart
I have had it plugged in all day and keep checking it to get the proper humidity
Thank you for all the help.
may one girl keeps laying her eggs in one corner and covering them up each day. The other girl just lays it in the middle of the duck house
But it’s getting colder and I was afraid the eggs would freeze or get to cold while she took her 7-10 days to lay her clutch.
maybe in the spring if she still wants to I’ll let her Broody her clutch
