Thought this was a brown leghorn until she started laying brown eggs

[SBFChickenGirl]

She probably is a leghorn. their first eggs are often brown and will become smooth and white!

Look at the pics. Not the right feather pattern for leghorn, nor does she have the white earlobes,

 

[SulkyBantam]

Yes apart from earlobes. L cross I think.

I'm so excited to know what she is! 4 days, 4 eggs so far! She's the only one.... The rest are getting their pay docked for slacking on the job....

Yes I believe you’re right; because they are a sex linked production breed they lay earlier than most as well. We got our first tiny egg from our black sex links at 16 weeks

That’s not true.
And she looks nothing like a Leghorn.
Don't spread false info.
