That's because you're pushing on her crop again. Don't give and grit/treats just yet. I don't start any treats until 2 weeks at least. It's very important for young ducklings to be on a good balanced ration. Purina duck pellets are excellent. You don't need to supplement with brewers yeast or treats.And yes she drinks like crazy...at least, up until now. She stopped drinking as soon as it started and every time I try to dip her bill in the water she coughs up the stuff
