Nice little eggs there. Congrats

So, I know typically it will be hard to tell who's laying what, but based on the fact that we have a Barred, Brahma, Orpinton, Wyandotte, Cochin, Bantam Barred - who all are listed as laying brown eggs and a silkie and Polish who lay white and cream, can I assume these came from my 2 little bantam girls? or does color mature with laying as well?

It would be hard to know which girls laid those first eggs. They could be from your large fowl girls. First eggs are small and will increase in size over time.
Generally the color of the first eggs will be an indication of what they will look like.

Something fun for your daughter may be to make a chart for each pullet with their name, record when they started laying eggs and record the egg weights. It's neat to see how much the eggs weigh at the start and how much the have increased in a couple of months.

I weigh all my girls eggs until they start becoming regular in weight.
I write it on a calendar
After they become pretty regular I just put a mark on the calendar so I know how many eggs I got that day.

I got a first egg from my NN pullet Emily today!
It was 1.3 ounces and cream in color. That’s Emily in the background.

Here’s Emily’s egg (cream) next to her sister Agatha’s egg (pink):

Everyday seems like first egg day to me... Got my eight gals new this spring (first chickens) and my first ever egg was from my RIR, she was 20weeks and it was a pretty good size cuz it was a double yolk....
Can’t get any better than that!!
