Adult feathers

[mykl1]

At what age does a turkey have its full adult feathers/colors

 

[Lagerdogger]

Feather color changes gradually for a long time, and even after they look adult, they keep improving. I don't have records on this, but I'd guess maybe 20 weeks until they start looking pretty much like the final product. Bourbon reds continue to get darker for some time, and the irridescence on bronzes also seems to improve for quite a while.
