So i've got a pair of ducks that i wasnt expecting to be laying eggs until the weather warmed up. Well i found a couple eggs laying out in the open when i checked on them in the AM so i collected those and looked around for more and apparently she has been laying them in little crevices etc. i found a few here and there and it appear she had multiple nesting spots around the same area of yard as well as dropping a few in their house. I got excited and started collecting them all to eat, i left 3 at one of her nesting spots. is there anyway for me to tell if she started incubating them, without a candle light or damaging the egg? if they are not started incubating, can i put some of the eggs into her nest box that she never used, to try and get her to lay more in there? can i take all the eggs from her different nest to put in 1 nest if she continues to lay them here and there to get her to incubate them? if i can not put the eggs in a nest with her, can i incubate them and put the hatched ducklings out with mom? if i continue to keep taking eggs will she keep laying through winter or will she only lay a certain ammount then stop and start laying more in the spring?
