:) With TwoTone being an EE, it is very difficult to see what breeds may have been in his background. With the large comb on the one side along with pea comb on the other (almost looks like his comb was trying to be a walnut!) he probably has leghorn in him. Here are some bigger photos of his sides. As he molts, he is getting more black and white on his white side and more white coming in on his "red" side :)
Wow, that is an amazing rooster!
