Green legs + crest makes me think she’s some sort of Easter Egger mix. Crest in those usually means some sort of Crested Cream Legbar heritage to get the blue egg gene. Color might be splash. What color egg did she hatch from?
She herself hatched from a brown egg, but some other eggs from her parent flock were dark brown and blue too, so I'm guessing it was some kind of a mixed breed colored egg layer flock she came from.
Highly unlikely, but since since you said she's from a grocery store egg and that the flock had dark brown/blue eggs... did she hatch from one of the Happy Egg Heritage Breed eggs?
Ah well, I'm not American, so no. She came from a small local store. We asked where the eggs came from and they said a local farmer. These weren't your typical production grocery store eggs, that's why I wonder what breeds this person may have had in their flock.
How fun! Large grocery store chains are the norm around here; I suppose the equivalent would be getting eggs from the farmer's market. How many eggs did you try to hatch? I suppose if you had the space/desire you could hatch several more and get a better sense of what genetics could be at play.
I put three under a broody hen. I didn't think any would hatch. Out of the three, two developed but only this one hatched. I did go back to the store to get more a little while later, but they said the farmer had quit raising chickens by the time I went back. I'm not sure if that meant chicken keeping in general or just that he stopped keeping his egg layer flock.
The blue spots she has (although hard to see in the pictures) look too dark to be diluted by lavender. I have several lavender birds in my flock, so I'm pretty confident she isn't lavender. When she was younger, she didn't have the blue feathers yet, which is why I thought she might’ve been lavender.
