I by far don't know much but I have a few questions that my help for the more experienced people on here that may ask you the same questions. 1.Have you checked his inner eyelids to make sure he's not anemic? You want to see dark pink to almost red. Anything less he may be anemic. 2. Is he eating well? Have you seem him chewing cud? It's a good way to rule out polio to make sure his rumin is functioning correctly. 3. Has he been banded if so is it all looking good?
