I could see buff brahma on the first bird but I don't think the second one looks anything like a cochin. Cochins are supposed to be fluffy puffballs, that bird is not. Could be a brahma mix. I can't see the comb very well, but at a year if it were a pure straight comb it should be a lot larger so I'm thinking mix. And the color isn't gold laced, it's a mixed color.
