bone/skeletal frame genetics? strengthening bone structure

[picalowpiepi]

i would like to try getting super sized poultry but unlike the meat chickens, I want to have the chicken have a good frame to support its weight. Does anyone have info on bone genetics? if not, which breeds usually have very strong/heavy bones?

Broiler breeds have about the strongest bone structure, what hurts them is the rate of growth and weight they put on, when I was breeding for such trait(Huge Chickens) I restricted their feed and even so they seem to put on weight by breathing air, that allowed the bones to mature, you can also try the classic Cornish, they have huge bones.
