my female duck has stopped eating! im at a loss of whats wrong with her! shes always been loud,pushy,talkative, and active...but iv noticed last night and today she isnt eating her food! she just stands there...shes drinking but not much...and i dont know if im paranoid or not but she seems to be thinner (which is horrifying cuz shes been the big breasted chunky duck)...i really dont want to see her starve herself...whats the cause and how can i make her better? i do have a male duck...is this a duck pregnancy thing?
