I have two Buff Braham Hens. Both sit low to the ground and are booted. The body size is that of a Standard Chicken, but there legs are short. have Silkies and Blue Self d'Uccle's and my Bantam birds are larger than these Bantams. Which one are they, Bantam or Standard? That nesting box is 4" high. Fluffy loves being a Mother to her hatch of the three Giant Cochin Chicks.
