Just got these 3 hens. He called them black rambler pullets. Also got two bantam hens. All three black ones have this issue to a degree with the worst being about a 1/4 of bottom beak sticking past upper beak. If you zoom in on pic, you can see the white of lower beak and black top part of upper beak. If the name black rambler isnt what they are, they may be black copper marans. They have feathered feet. I need to know if this is accidentally broke off or could be a disease they could give to my current flock.
