My buff orpington duck are 17 weeks old and i hatch em myself. I thought it was a drake because it sqeeches and not quaking. I have 3 other ducks and 1 is quaking which iam sure it is a hen. Could the buff be a hen because theres no drake feather at all? My other two that sqeeches already have drake feather that curls up on their tails. I was wondering if i have a buff hen?
