At 13 weeks, yes, I think that pullet is a good guess.We are not sure if this is a white leghorn? Any thoughts? Pullet? 13 weeks old...
And yes, she looks like a leghorn, she:
-is nice and streamlined
-has bright yellow legs
-has white earlobes
-is bright white (yes, they come in lots of colors, but white is most common)
-her single comb is already getting a good size (and yes, they also come in rose comb, but single is much more common)
