I posted these chicks last month, now they are 4.5 weeks old. They were mistakenly sent to me by Welp. Can anyone tell from these pictures, I know they aren't the best. I looked on feathersite http://www.feathersite.com/Poultry/CGA/Arau/BRKArauChik.html and am wondering if the grey ones are Araucanas? The other 2 look very similar, black with brown collars. But the birds with more light brown faces have yellow legs. While the others have slate legs. The slate legs I am thinking again Araucanas. But not sure on the other, Partridge Rock? Thanks for all opinions!
