Need some others opinions and/or expertise! One of our ducklings that were hatched from a batch of 10 is significantly smaller than the rest of the batch. I don't know whats wrong with it, or if its a dwarf or what. They are 4 weeks old, but this one looks like its only about 2 weeks old. It seems to drink fine, but it definitely does not eat even half the amount the others do. When they are out foraging, it may grab a blade of grass or two, but mostly jsut stands amongst the batch all hunched up. It will follow them wherever they go and starts peeping loudly when left behind. It can't keep up but tries like hell. We have watched it with the duck feed (pellets) and it eats a few, but seems to eat only one at a time. I gave it a dish of the starter/grower crumbles back to see and it did eat more, but still would take very small mouthfuls and shook its head sometimes after taking some in. The mama duck takes good care of it and does not like to be separated from it. Any ideas?!
