After reading through this forum, I am anxious to get more feedback. My ducks are about 1 1/2 years old. I have five Pekin/Mallard hybrids. Two males, three females. I have a raised pen that they go into at night (they line up on the ramp at dusk ready to go inside!!) and I let them out first thing in the morning. I have always left food and water inside their pen, but not in their sleeping area. Currently we have the inside of the pen lined with wheat straw and we have to clean it out about twice a week. For those who have replied to this question and are knowledgeable, you are saying we can put them in at night without food and water? That would save on the constant cleaning and cost for straw and food!! My ducks are huge! I don't know if it's because they are spoiled rotten (since we give them food and water all night long!) or just the combination of the hybrid. They swim in our pond and forge all day and only get the feed and water at night. Any suggestions? Would it be ok to have them go without food and water at night and just leave their feed out during the day when they forge? Thanks for any response!
