Interesting egg color question

[HenHouse10C]

This morning I got 2 first eggs! Pretty happy about that but I don't know who they're from. I have 2 black pullets who are now 22 weeks old, that I always assumed were sisters because they came from the same brood and looked the same except one is bearded. I have no idea what breed they are.

Well the eggs I got this morning were pinkish tan and greenish blue with brown speckles. Would it be possible for them to lay such different colored eggs if they are in fact sisters? Or should I be suspicious of one of my other birds?

Here's the eggs

The two girls I suspect:
Lucy, she has a single comb and is super fluffy

Black Betty, a little slimmer (couldn't get a body shot).
What kind of comb would this be? Would that make a difference in egg color?

I will add that I also have a white leg horn + blue copper marans mix around 4-5 months old, not sure how many weeks. To me she doesn't look ready though. Then I have a 15 week old mutt who may be a BSL, and a 14 week old Lavender Orpington.

If they from the same mum and different dads then yes. If they are from those 2 hens the blue one will be from the bearded chook as that trait is more common in blue egg paying birds.
Easiest way to be sure is if you can isolate the chooks in question for a few days, or a least till you get an egg.

They are both Easter Egger mixes. The gene for blue/green eggs is usually inherited with the pea comb gene. That last picture shows a pea comb. That is your green egg layer. Single comb birds very rarely inherit the pea comb gene.

Well, this morning I caught the bearded girl in the act - she lays the cream colored eggs! Now to watch the other one to confirm...

Wow - that's a suprise

That's exactly what should be expected. The Lucy, the single combed bird did not lay a colored egg. Black Betty with her pea comb is your colored egg layer. The blue egg gene is located very close to the pea comb gene. They usually get inherited together.

Thanks for your wisdom! They are such interesting creatures!!
