Another silly question.
My Drake Khaki has just began getting a green head. 1. When will he become fully coloured and how old would he be?
2. Can he get my female Fertile?
They get their colors at around 4 months if I remember correctly, and yes, he will be able to get your duck fertile, though it'll be a couple more months before he can.
My Cayuga just got his colors and hes 7 weeks (:
