They look pretty nice over all, but these pics arent the best to see their shape and overall type. The only things I really noticed about them is the comb size. Cochins arent supposed to have large combs like that, they are supposed to be straight and medium sized with 4-6 points(I noticed your male bird has 3 points on his comb, and alot of Cochin breeders have told me that you will get some of your best birds from a 3 point male bird). The male has a pretty large comb for a Cochin and it seems to lop over in the back which isnt a really bad thing, just something to take notice of. And the pair also seem to have a little bit of white on their earlobes, it may just be the pic that makes it look like that, but if so that is a no no for Cochins, they should not have any white at all. The hen also looks like she has a split in her breast feathers? Her breast should be smooth without any spilt in the feathers. It ist a major flaw, just something again to take notice about. Overall, you have a very pretty pair of Cochins to work with. Just remember, these might not be show stoppers, but they might produce some for you. Good luck and congrats!
