Walt,
The darks and the white are a little over a year old. I know what you mean about the White being shallow and I feel the same way. (I only picked her up because of her head shape and width. Honestly, I am not sure I want to raise Whites.)
My dark hens seemed to have gone that direction (shallower) too. I only have the two dark hens. The latter pictures, of the dark hen, are of the same hen. The other one, did not want to pose on the stump for me. Of course, she would be the better of the two, but not by much!
Walt - how much is genetic versus feed? I ask because I am not free feeding them as the breeder did. Plus, I have them on a strict and measured 75% grain, 25% pellet diet like the rest of my Orientals. I feed my Orientals, this time of year, 4oz of food per 5lbs of bird. My Ko get 1/4 cup each of mix a day. The Cornish get 1/3 cup each per day.
Thanks for the feedback
Some will probably disagree, but I feel it is all genetic as long as you have a diet that is reasonable. If it works on the Ko's it should work on the Cornish.
