I'm sorry, Iknow this post is from months ago, but I'm having the same trouble with Nankin chicks pecking each other...what did you do to stop it? I've already given them much more space...did increased protein help? thank you!
My daughter is working on a Nankin breeding program; just got 25 chicks from a fabulous Nankin enthusiast. We would love to be in contact with others interested in this sweet little treasure of a bird! New to this realm of communication, so pardon any errors in etiquette...
