Ok, i've seen many of you guys want to breed your ducks and get ducklings. Well, i managed to get all 6 of my ducks to set every spring for the past 2 years. I think these few things will help get your ducks to also set: 1) Tall grass Ducks feel they are hidden and well protected in tall grass. If any predator approaches them the grass will move and they can notice. The duck will rotate to face the predator and attack it. You don't need to leave their entire pen tall just a little section. Also they use the tall grass to make really nice nests. 2)TemperatureMost Ducks like to set in cool weather (60-75 degrees). Don't expect your duck to start setting in the middle of summer. Some ducks may. Those ducks will need extra water brought to them. 3)Male to female ratio Most Wild ducks do not mate for life. Most wild mallards don't even mate for life. Infact the only known breed to mate for life in the US are snow ducks. I read once that it would be a perfect world if every drake could have 2-3 ducks. Also this way if the male gets bored while the duck is setting he will have some one else to bug. 4) Clean water This is just to bring up the fertility rate. Ducks breed more when wet. Thats all i can think of for now. If you can think of anything to add, feel free. Hope that helps!
