So the fab 5 are about 8-9 weeks old now. Our big male drake is about 3 years old. At what age do I need to start watching to see if my male to female ratio becomes a problem? The fab 5 have all been raised together and Jmatt, my big drake, thinks he's a goose and hangs with the Canada geese that passes through for the most part and only comes around for some loving occasionally. Jmatt is an equal opportunity lover, he'll grab whoever he can get, drake or hen. All together I have 4 drakes and 2 hens and I'm wondering when it may become a real problem.
