my ducks have layed each day for the last 2 months, but today one didnt lay is thia usual

Yeah this is normal their is nothing to worry about. ducks only lay so many eggs a year so will not lay everyday, sometimes they lay eggs for ages then have a break from 1 day up to a week, or lay one day then miss a day for so long but then lay everyday again, plus ducks sometimes stop/ slow down when moulting.
Also ducks that sometimes lay two eggs aday will stop for a while eg 1- 2months.
It all depends on the breed of duck some will lay in winter some wont etc.

cheers
