Stroke is an abrupt interruption of constant blood flow to the brain that causes loss of neurological function. The interruption of blood flow can be caused by a blockage, leading to the more common ischemic stroke, or by bleeding in the brain, leading to the more deadly hemorrhagic stroke.
Most ducks do not start laying eggs until they are between 9-11 months old. Depending on the breed they can lay year round. A duck will lay an egg a day until they have a clutch, between 8-15 eggs and then the mother will sit on them.
Update: I have 5 Runner Ducks, and 1 Drake. They are now about 17 or 18 weeks old. I also keep chickens, which normally come into lay at about 20 weeks. As ducks live considerably longer than chickens, I wondered if the age at which they begin to lay was correspondingly longer.he wings are small and held closely to the body. Indian Runners are egg laying ducks and may lay close to 300 eggs in a year. They should start laying eggs between 4 - 6months.
