I got a Saxony duck about two months ago, and she has been givining me a green egg every day. About a week ago, she started slacking off, laying every other day or so. Well,one day last week I went out to the coop to find she had layed 3 eggs, in one day! Her eggs are large, green, and always layed in the same nesting spot. I check every day, so I didn't miss one. My other duck is a Silver Appleyard, who has yet to give me any eggs, so these eggs are coming from my Saxony girl. Do I need to be worried about her?
