My big boy is really ill. To narrow it down he can't hold his head up. Is not alert at all. No eating or drinking. Just sleeps. Has mucous coming from nales. Ive been giving him electrolite for some fluids but it has to injected. 20 cc at most. Poop is yellow liquid and a drop of solid something. His head is really hot. I tried the crop cleansing but doesn't seem to be issue. I thought it was heat stroke as he had been in the enclosure with high90s temp direct sun. I'm doing everything I can think of. He is having difficulty breathing. Please help. Have no vet either that treats farm animals.
