Yeah, I wondered about it too. It doesn't seem to show saddles in the photo, but it does have kind of a gangly roo look about it. At first blush I thought roo, but then I didn't know.
Hard to know from the photos and with the poor care the birds received...plus we have no idea of age.
Game roosters usually have some pretty whalloping big single combs...but with these mixes....who knows.
To OP if you could give us a full profile with tail (especially) we could maybe guess a bit better on the brown mottled.
