I wouldn’t use the paint. It would make it harder with the single comb.I also have some chicks that are in the brooder 5 weeks old. The rooster I plan on moving up is in there, he is black with no vault from hatch, but he has correctly colored skin and feathering. I think there are at least 2 other males in there with him. 1 is a paint male and I have a blue and a cuckoo that I can't confirm. The paint male is very nice and has plenty of black patches coming in, but he has a straight comb. I was planning on breeding him to blacks for splits and then back again to him, but will it be harder to get rid of the straight comb?
