We are new to raising ducks. We have 5 Muscovy ducks, 3 girls and 2 boys. They are about a year old +/-. They started breeding like the dickens about 2 1/2 weeks ago. These kids are busy, busy, busy! They free range, but we have checked everywhere they have access looking for eggs to no avail. QUESTION: Is there and average length of time after they begin to breed, before they begin to lay eggs??
