Got a little crash course in duck genetics yesterday. Super interesting stuff.
The whole impetus was that we ended up with 3 black ducklings and none of the parents were black so I was like, “what gives? Are these the mailman’s babies?” 🤣
Turns out Blue Indian Runners don’t breed true and a percentage of their offspring will be black or silver instead of blue.
