Maybe a mix of both? look close to my KCs, but patterns and colors off some or just way photo is, and yours look lot thicker than mine.mine or are just fluffy or plump (wish mine would plump up like that but think mine crossed back more for runner egg production). Beautiful though, and am wondering about their laying size and frequencies?
Two of them look like buff drakes. They look similar to the ones I used to have. The other looks like a KC drake. How old are they? It may take some time for their full colorings to come out if they are young.
If your getting an egg a day then they are KC enough for me. meat maybe a factor as well as laying at early three to four months six if late bloomers i hear. mine are just somewhere over a month and behind on growth, so i don't know much about them other than they're horrible when inside at about a month. lol. Water flinging filthy lil boogers but got addicted to scovy eggs and hoping these are as heavenly!
