A few weeks ago our duck started laying. We got 4 eggs from her and found a piece of the 5th in their pen which they share with our pair of geese. Last night we put 5 chicken eggs in their pen to see if they disappeared and this morning all that remained was a bit of shell. This evening I put in 1 chicken egg after bringing them in for the night. The gander walked over, cracked it open, and then left it for the ducks to eat. The ducks weren't interested in the egg until he opened it. The goose wasn't interested in it either, but did scold the gander when he cracked it. Do you think he'll crack open the goose eggs when his mate starts laying? We've moved the ducks into the chicken coop and we'll be putting them in separate pastures.
