Heritage Plymouth Barred Rocks would probably be helpful with what you want in size. They're huge.
I'll have to get some pictures of the Rooster, with me holding him. I'll get a measurement too.
If you want to use Jersey Giants you can do that too.
Giant Silkies, & I will be adding Malay once my first Larger Silkies are produced.
I want the Roosters nice, & large to breed the Malays pullets easily.
