When do the pointy saddle feathers start coming in?

12-14 weeks is when the first male feathers would be popping out from under their young feathers.

 

is 12-14 weeks true of slower developing birds as well -like brahmas?

 

you can sadel feather sex most birds by 3/4 mounths some at 2 mounths

 

I've seen them start to peek through at around 10 weeks old on my Barred Rocks. If you part the back feathers, you may see the pointy, shiny feathers starting to break through at around 9 weeks old on some breeds.
