This past April, I became the proud owner of 2 baby Rouens, which turned out to be a male and female (just my luck). The male is quite tame...eats from my hand, lets me pet him, etc., the female was slightly more shy but I was still able to pick her up and handle her fairly regularly. Since my ducklings were old enough and the weather warmed up in May, they have free ranged in my back yard. They typically stay close to the house, since their kiddie pool and food are always nearby. Just yesterday I returned home around noon for lunch and only my male Rouen came running up to me. Normally I ALWAYS see the 2 ducks in pairs, they've been inseparable since I raised them as ducklings. So something immediately seemed off when I saw my male Rouen running toward me alone...I walked all over my 2 acre property (surrounded by cornfield...both ducks take shelter in the corn during the day, and sleep in a dog house inside my garage at night), trudged through the corn rows nearby my yard, no sign at all of the female duck. She literally vanished, without a trace...no sign of a struggle, feathers laying around, etc. Being in a rural area I know that predators are around, but they typically stay far away from houses, especially because my surrounding neighbors have dogs, and there is plenty of other food available (rodents, frogs, you name it). My neighbors also watch my property like a hawk when I'm at work during the day, and they saw no unusual behavior or anything out of the ordinary yesterday. IF my female Rouen happens to be nesting/brooding, is it normal for her to be completely gone while the male just wanders around continuing his daily business as usual? How long might she be gone before returning, and would a duck set up a nest fairly distant from her home where she's been since April without incident? The male Rouen been very clingy toward me since his woman vanished yesterday (he literally walks under my legs when I'm walking through my yard). I understand that it's possible she was just nabbed by a predator (I doubt any of the hawks in my area would've taken a duck that size with ease, and that would've been noticed by neighbors in broad daylight), but considering none of my 7 chickens were touched, the male Rouen was perfectly normal/untouched, and the vanishing would've happened mid-morning yesterday, it's tough to conclude that a predator was to blame. I'm more interested in what the nesting behavior is like with these ducks...thanks!
