One of our embden geese attempted to hatch out goslings a few weeks ago. She kept breaking the eggs so we removed the dog house that she had been nesting in to break her broodiness. She looked rough when she emerged. She had lost weight and her feathers were a mess. She rejoined the rest of the flock and appeared to be back to normal. She ate, she drank, she hissed at the dog. She has been losing a lot of feathers, we assumed it was a molt brought on by the time she spent being broody. Today, she has been in the goose shed all day. She is very, very weak. We hadn't noticed any problems with her other than the feather loss until today. Any thoughts or suggestions as to what we should be doing?
