Our mallards have started to lay eggs for the first time. We want to hatch out the eggs. Should we let eggs stay in pen or collect everytime we find one. Found 3 yesterday 2 today. Weather is cold 30s at night day time only 50s and expecting colder weather since its only January 28th. We live in So.Md. Surprised the ducks have started this early. Should we collect or not they are not being layed in a nest just throughout the pen. We have made up some nesting boxes in hopes they will use them. Any suggestions please.
