I have2 brown ducks and they started to lay eggs. 1 per day in the garage and one that died in the water. They are locked in the fenced yard during day and I put them in garage at night. They typically lay at night. My thing is they have not laid in 2 days and only 2 are in a nest they started to build after they laid them. Will they lay more or will they hatch?? How will I know?
