This is from the ABA BANTAM StandRD which has the rest of the Dq's and Defects for Mottled as well as the description of the female mottled Cochin
It will take some doing to find birds that fit this pattern and I don't thinkl just any color will do
I always found the Mottled with width of back and breast to be a superb color varity of cochins
you should not have any problems finding some there in Tennessee area
there is a poultry show at a little town south of White Pine Tennesse once or twice a yr
Any question on this email me
