I have a buff Cochin that has white on its feathers. #1 Is it a buff mottled? She is not quite this dark (and the chicks belong to my d'Uccle hen). AND........ #2 What breed and color is this chick also 6 weeks old? It is a purebred bantam, not a sex-link. It has a single comb and very gold legs along with a few white spots on the ends of some feathers.. Thanks for all of the help I can get!
I think that your Buff Cochin is still a Buff Cochin, despite the white feathers. Many buff birds have some white in them, especially in their first sets of feathers. As for your other chick, I don't know what it could be. I would recommend posting new photos in a few weeks; by then it may be easier to tell. Also, in case you were wondering, your Cochin appears to be a pullet, but the legs on the unknown chick are looking cockerel-ish.
The cochin isn't mottled, it's just juvenile plumage and will sort itself out. How old is it? I'm not seeing much comb yet, but the patchy coloring makes me not rule out rooster yet. The second bird could be any number of breeds or colors at this time, but I agree those are some thick ol legs!
Both chicks are about 6 weeks old. So all of the white on the 1st chick will go away? I have 3 others that are all just buff. I will get some new pics tomorrow. Getting a little late for pics and soo they need to go to bed and the dog crate they live in for now has to be put back in our garage.
