Hi all I am new to the website and to raising ducks. We bought 2 Pekin ducks the beginning of March. The past month one of the ducks has been laying eggs. We think we have a male and female because we've seen one on top of the other in the pool. The female sits on the eggs but not all the time. I thought she would eventually stop laying eggs but she hasn't. I think I counted over 30 eggs this morning in the nest. My question is if I should take the eggs out of the nest or leave them. We're not sure if they are fertilized or not. One of the eggs is getting darker in color. Could that be a duckling or is the egg going bad?
