Breed of Roo with no tail feathers?

[newTexan2chickens]

This mixed roo does not have the tail feathers the others have (same age). Is he just late to get them or will he not have any? He has been crowing for weeks and is now pretty darn good. Guessing he is about 10 wks give or take. He has feathered legs if that helps at all.

well it is a boy, and its tail feathers are growing, just slowly. My RIR's are that way.

I have three roos that just got tail feathers coming in at 11 weeks. Don't know why they are sooooo slow to get them.
