Hmm well I'm beginning to think maybe my Red Leghorn rooster is wheaten split duckwing? What would explain the 4 chicks I have hatched out right now to look like dark brown leghorns? They are red but with very defined, very strong duckwing pattern.Mine where red but you could see some stripes.
Years ago I crossed buff with browns. The hens matured looking like browns but about 1/3 of the bird starting from the front was buff.
Sorta like how black sex links hens get color on the front. They were some of the prettiest birds I've had.
What do these look like to you?
