They're lovely Light Brahma pullets. By the way, they are more beautiful, friendlier and nicer than Leghorns. I honestly don't know why anyone would want Leghorns, myself. You got a deal! My grandmother has a sweet hen named Dumpling and she's the best hen in the flock.
Yep, Brahma pullets. They won't reach the production levels of Leghorns, and lay creamy tan eggs instead of white. But, as stated above, they're usually calmer and friendlier.
I just got one light brahma from the feed store about six weeks ago. She looks almost like yours in size and coloring. I think they're beautiful and I love the feathered feet! She's already pretty sweet too!
