I've been raising two Mallard . one he and on she. I supprisingly look in thier coop and mama was just laying there dead. I cannot figure out why she did this. All the other chick and guinieas are fine . Daddy duck seems to be lost. I'm afraid that he will fly away now looking for another mate. All my critters are free ranged and go back to thier coop every nite...Mistery I'm a new egg and would appreciate any feed back cause I'd like to know..????
