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.
Egg Laying and Incubation. Soon after the nest is finished, the female will begin laying one pale blue egg a day in the morning over the duration of about a week. After ALL of the eggs have been laid (usually 4-6), she then begins to incubate them for 13-14 days, taking breaks to go feed.
