~I looked up saddle feathers so i know what you mean now, i have no idea what to do with them now. none of them are crowing (they should be by now i assume if they are male)
Oh poor you - Not too many option! Freezer came to mind! - I had 6 chicks and 4 turned out to be big old roo boys. I had to find new homes for them. My Maran chick had a big fluffy butt. That bird would squat like a girl but it also had those horrible old boy feathers speckled hen was talking about and it would do that Roo boy dance? We called it the He/she bird. After we got it a new home because it went along with another hand reared bird it finally started to crow! It was 9 months old! We couldn't keep Roo boys here either.
Oes - best of luck finding homes!
