So next spring my family and I are going to be getting some domestic Mallard ducks. we know where to buy stuff and how to take care of them but we can't find any place that sells large quantities of straw or cardboard bedding. We need bedding since we live pretty far north in America and have bad Winters. Can anyone tell me where they get their poultry litter? Thanks a ton for any help you can give me. Also we need to know a good way to keep brooders dry and somewhat clean.
