Yes those are cuckoo also
The hens are expressing BIRCHEN in the hackles. Maybe your roo is too. Can be harder to tell in males. I usually don't breed birchen cuckoo hens. That is not the desired look in Cuckoos. They should be evenly barred all over like barred rocks. I see a couple of cuckoo looking hens. The third pic down has 2 in the back ground. Your roo looks like he has some gold leakage too.
