Hi everyone, I've been using a duck tractor for my 4 welsh harlequins for the summer, moving it daily and hosing away the poop. But my lawn isn't coping very well and it occurs to me that it will end up a big boggy mess in the winter. I'm thinking of putting chicken wire on the bottom to prevent predators digging in and then adding deep litter of wood chips and peat moss that I dig over daily. My question is do I need a roof over the whole pen? Does it matter if it all gets wet for the composting and the ducks? Also is chicken wire necessary on the bottom? It would be easier to get the compost out without it.
