Hi, I’ve got two 2 week old Indian runner ducklings. When I pick one of them up or press on her chest she vomits water and food. They have imprinted on humans and absolutely love being cuddled and held, I was hugging her (not too tight tho) and she was sick a lot. The other duckling is always fine when picked up and I’ve never noticed him being sick. I was wondering if it’s anything to worry about? It’s been this way ever since she hatched...( she did hatch early and hadn’t absorbed all her yolk and still had her umbilical cord.) thanks x
