Oh yes that is way too much drakes. Depending on your weather they can get sexually active early. We have really soft winters the last years; so most are going at it the whole year. It used to be; ducks born early in the year (spring) may or may not lay eggs/being sexually active untill the next spring; but had a good chance to do it the same year. Ducks born later in the year (summer/fall) probably not the same year. Due to soft warm weather they are ALL at it between 4-6 months. No egg-pauses or shedding anymore.. the weather is too off/nice to slow them down.I had 3 ducks before I got these, so I have a total of 5 females and 6 drakes. I knew I would have too many drakes, I just thought it wouldn't be this soon for them to start fighting. Ugh. Time to weed them out. I will only keep one drake.
