I saw the duck on sunday night 8pm and the next morning I found it missing. No traces of feathers or blood. She statyed with our 3 month chickens inside our compound. The chickens were staying in the same place and not scared. There are no predators except eagles, crows and cats. The cats only attack the small ones and never bothered with the adults. The duck is 1 and half years old. I checked our neghbouhood and found no feathers or any remainings. Is there any chances of survival with less or no water, if it wandered away?
