We have a brood of muscovies with a mama duck, hatched out by her and everything. Theyre probably a month old or so. They lived in an enclosed area, away from predators, etc. Now the ducklings keep dying, and I cant figure out why. There arent any marks on them, they just lay down and die in a process that take only a couple hours. This morning the ones that were left were doing great, and now theres another little weak guy. Ive raised chickens for a while, so i have some poultry experience. We also rescued a couple wild mallard ducklings two years ago and raised them fine. Whats different about these ones? They look completely healthy. We bought them from a lady who was downsizing her flock, but the conditions were good there. If anyone needs any info i havent thought of, go ahead and ask. Thanks peeps.
