First time silkie hatcher! Chicks seem small for lockdown age

[Helenhowes0]

Hi all, im at lockdown and I candle my eggs before lockdown and the chicks inside seem very small for day 18. Ive had experience with hatching pekin bantams and I would say compare to them these eggs look like they are day 14 size rather than day 18size. Is this normal? Im using the same incubators as i normally do never had an issue before.
Are silkies eggs just naturally smaller? I would say they are filling up just under half of the eggs space where as my previous eggs would pretty mich fill all of the space apart from the airpocket.
Any advice or reassurance would be greatly appreciated

Do you have any pictures of the eggs?

I don't know if it helps, but here's a pic of one of my smallest day 18 Silkies this year. This one hatched out just fine and at the same time as its fuller egg siblings.

Hi, i do.
I think whats throwing me off is the huge spaces on the sides

The air pockets look wonky on a few of them. Did you get these eggs shipped?

 

[Helenhowes0]

I did get them posted yes

 

[FarmerGirl101]

Did you let them sit/rest before setting them?

 

[Helenhowes0]

I let them sit for 24hours pointed side down. Recieved them on the 2nd of September put them in on the 3rd

Its day 18 tomorrow technically but I like to candle them the night before lockdown
