This morning, Wobbles began opening her bill wide and throwing her head forward, almost like she was dry-heaving. Well, it just happened again only worse this time, she was FLIPPING OUT, throwing her head back, walking backwards and sprinting all over in a total panic! What can I do? My vet isn't open until tomorrow and I've called every single clinic within 30 miles, no one's open that can take exotics. She's breathing ok, but could it be sour crop? Would that induce gagging in a duck? Should I give her olive oil? Please help!!
