My African Grey is very sick with diarrhea. I have contacted all the vets in my area & no-one knows what to do! I'm desperate! It has always been a very healthy bird. I am giving it water with Rehidrat and probiotics but this is only treating symptoms, I need to deal with the cause - could it be bacterial, parasitic or a toxin? It started with food being vomitted up 2 days ago and then watery diarrhea. Should I try an antibiotic? Now it is very weak, feathers fluffed, sitting on 2 legs in one place. No runny nose or breathing problems. Someone may have given it a cheese flavoured puff crisp - could this be toxic? Any advice gratefully accepted. I'm frantic!
