My pekin duck started laying eggs 5 days ago. For first three days she layed a perfect egg in the morning but now the last two are very small and the shell is very soft. These are my first ducks so I was just wondering if this is normal, the last egg she layed in the pool. I know they don't lay much this time of the year but we were very excited to get our first eggs and the first three were so good! Thanks!
