How Early Can Good Tail Structure Be Determined?

[Steve Neumann]

I am starting to notice that many of my chicks that are narrow in the rear are producing a lot of the pinched tails and tails with poor structure.  Is this something that experienced breeders cull for out of the brooder or is it unwise to assume that these birds will develop bad tails?

[Mike Gilbert]

If the parents exhibit good tail structure, I would let them develop.   Those juvenile feathers molt out and new and additional ones grow in.

I agree with Mike.  Tails aren't as important as heads.
