Hi! I'm new to raising ducks. I have two Khaki Campbells one drake and one hen. My hen just started laying. How will I know if and when she is broody? Will she hatch her eggs? Her eggs are pushed all around her pen. Is it ok for me to touch her eggs if i want her to nest on them? Her eggs are different sizes too. Is this normal when they first start laying? Thank you so much!
