Sorry, I am not familiar with the breed. You can post at "what breed or gender is this." Give age of bird in photo to help them access gender characteristics.
Welcome to BYC. Glad you decided to join our flock. From what I can see your bird looks like it is developing red earlobes; if so it is a Welsummer as Brown Leghorns have white earlobes. Please feel free to ask any questions you may have. We are here to help in any way we can. Good luck with your Welsummer.
