I need to know if anybody else has had this problem, and what may be causing it or what may help stop the problem... So I have found 3 eggs so far, and not all from the same duck, in the duck yard probably from the late afternoon...no big problem, right? well, these eggs are missing their shells, they just have the outer skin it seems, but no hard shell... so you can squish the egg-which is still in an egg form- and not break it, I threw the egg I found yesterday at my compost heap and it bounced off the wall and bounced away without breaking...these things are so weird. What is going on with the lack of shell? my ducks are on layer pellets, they generally lay very thick shelled eggs at night or early morning and those eggs that I get out of their coop seem great. ANy help would be appreciated.
