Help me understand the genes!

So I bought a “gamblers dozen” eggs locally that can be the following:

Purebred cream legbar
Cream legbar hen x BCM Roo
BCM hen x cream legbar roo
Pure BCM

It was hens choice.
Hatch day was yesterday and I was able to see who came out of what egg and I was wondering if anyone can help me figure out what they may look like as adults I put my guesses in there but I’m not sure I quite get what to expect with how the feather patterns will be as they get bigger and there wasn’t many pictures when I searched.

I’m going to add each chick separately but here’s what we started with. I’d like to update the thread as they get older so others can have an idea too.

(Also - the nest has been changed to something more chick appropriate now that we hatched )

I wrote my guesses on some so I can track as they get older

I’m thinking male? This hatched from a legbar egg so we definitely are cross here

What I think may be a pure cream legbar , male.

Legbar egg, pullet? Guessing pure legbar

This babe was from a marans egg so definitely a cross of marans hen x cream legbar roo but I’m thinking pullet. She had a black outline over her chipmunk stripe. Pic of egg provided.

If it hatched from a legbar hen and a marans rooster, it's female. Males of this specific crossing will have a head spot, females won't. However
The ones with a marans hen under a leg bar rooster will all have head spots

Definitely legbar hen.. and had to be marans rooster with the black feathers is my guess. I included the nest picture with the two blue hatched eggs so we can see it was definitely a legbar /marans.

My marans hen egg hatched a chipmunk striped baby so guessing that one was a marans hen and legbar too. She had a beautiful black stripe around the chipmunk stripe. I’m confused for sure

Because legbars carry the barred gene- if the BCMs and legbars are purebred- you have a little pullet here! Cockerels would be barred/chipmunk, and pullets are black and will mature to a BCM-looking hen.

Here's the genetics calculator showing the cross: http://kippenjungle.nl/kruising.html?mgt=E:E^R/E^R,Mh:Mh/Mh&fgt=E:e+/e+,B:B/(B)

Barred genes make this one interesting! Crossing a barred (crele in this case with legbar) on a BCM results in crele/chipmunk for both cockerels and pullet chicks.

The next generation will be darker red than the gold on legbars, but largely the same overall look.

So... based on your eggs

Pure legbar- chipmunk chicks
Legbar rooster X BCM- chipmunk chicks
Pure BCM- black or tuxedo chicks
BCM rooster x Legbar hen- tuxedo or black pullets, and chipmunk cockerels (sex linked!)

Oh yay, so the black legbar hen/BCM roo baby is a pullet!
So based on this, we have 3 pullets, one rooster?

Thank you for sharing your knowledge and the calculator. We have had roosters for years but he was a bantam and couldn’t do the job for the ladies so never paid attention to genetics /feathering /eggs
