I went outside a bit ago and only 2 of my ducks were in their tub swimming. The temps here have been in the 90s for days. I looked for the other duck and found her inside the duck house with vomit everywhere! I picked her up and misted her with the hose and cleaned her up and she cannot stand. Is this heat exhaustion? Right now she is inside in the bathroom tub. She is no longer panting and I'm hoping it was just the heat that got to her. Although I did find a small piece of metal in her vomit. I'm thinking it was a piece of a melted aluminum can from our firepit that we noticed she got into this morning. Any information would be helpful!
