The Great SI (Shape index) experiment

[Nksg75]

I've measured my eggs and they are now in lock down. If I do a rough guestimate of the numbers, anything below 3.XXX is a cockerel and anything 3.XXX and above is a pullet. By that estimate I'll get 5 to 6 pullets from this hatch. One egg is on the bubble of being below the 3.XXX number. Not counting my chickens before they hatch...just saying

3.081863 - olive
2.909887 - olive
3.017713 - olive
3.00972 - olive
3.047242 - blue
3.004337 - blue
2.851936 - blue
3.131795 - pinkish
2.894093 - pinkish

Predictions:
The 2 pinkish eggs = 1 pullet & 1 cockerel
The 4 olive eggs = 2 pullets, maybe another pullet and 1 cockerel
The 3 blue eggs= 2 pullets, 1 cockerel

Now I sit on my hands and wait...

Huh?
I am lost on your numbers?
Did you do the measurements on both width and length?

Yes, please show your math so we can see how you arrive at your index.

They are super fast too with the results.

$11.00?
Wow, that may just be worth it!!

Well we had to take a side detour here due to a delayed hatch with a pip already started and nothing for 15 hours at all but squealing, not chirping). I had to intervene with helping to zip and pop out. (first time and hope never again). She made it!! It was a complete learning experience on my end. So far I have 4 chicks and 1 left to hatch. Three are for sure pullets (autosexing) and my marans I will know at the end of the week since I mail in the shell for DNA. (great company for $11 does this). I will post everything when all is said and done!

Boy o boy this really catches my attention.

@Cot Cot Have you used this service before?

Ok, so to clarify how I was calculating my info:

Remember this is in mm, not inches

Then here is what I use the ole calculator for:

Here are the measurements for the eggs in the incubator now.
I have not finished calculating the last 2 pages, but will get it done soon enough.

Yep, that is exactly what I used. I am waiting for #1 to hatch out of the six. So far I have more pullets than cockerels but the story is not over until this last egg and possibly one more comes in.

YES and they are GREAT! Have two shells in the mail out tomorrow. They are so quick I should know by this Friday.

I measured the same way you did but I did mine in inches instead of millimeters...that's why the numbers look different.
