Muscovy Ducks Aren't Laying
Where they laying before you got them? How old are they? It's likely the move caused some stress so they would have stopped laying for a couple weeks.
Egg laying has more to do with the length of the day then the temperature. Ducks need about 14 hours of sunlight to lay.
If they are of laying age... Have you checked your yard for signs of a nest? They could be laying under a bush or something. Muscovy are notorious for brooding so they are going to want to start laying a clutch of eggs in secluded spot. You may need to go on an egg hunt.
Thank you for the suggestion! I'm thinking we are having a photo period issue combined with the stress of their recent move. I found some solar powered led holiday lights that i plan to string up in the coop to increase day length. We will see how it goes.
I have thoroughly scoured the yard, no hidden nests.
The important questions that weren't answered are how old are they and were they laying before?
