Went out to the pen and this was floating in the pond. I know its a shelless egg but do i need to be concerned? One duck is unknown age afult and two started laying last fall. The size matches the oldest pekin but tge other two have been gaining size and uts water logged. (Iphone wont let me correct spellings here??) are they lacking something or ill? Yesterday i built a ten by five pen next yo them so maybe stess? They only appeared very curious. The mowing was a littke bothersome to them.
