Better prepare yourself. Ducks will lay when and where they choose. I have actually seen a duck walking across the yard and plop, there is an egg and she did not miss a step. The will also lay in the most out of reach and out of the way places, especially if they discover it is you taking their eggs. So, be prepared to crawl, scoop, roll, reach and anything else to gather those eggs. Around here every day is an egg hunt.
That is the truth. You very seldom find them out in the open on occassion I do. I hold it up and say thank you. Sherry is my consistent egg layer who lays in the same spot. Bless her little heart but still I have to bend over and reach under the little bush. I hope my neighbor across the street knows I'm gathering eggs.
