No, it is not normal. How much weight have they lost from the time they started losing? What are you feeding? Are they eating normally? Do their poops look normal?
Well.. They are all very young chins. Probably 7 months old. Both was like 490 grams in the beginning of the month. Now only 460grams. I had change their pallet source to APD timothy from alfy. Now they eat less pallet as in really less 20% of their normal feed. But they are eating lots if hay. Other than this they look to be okay. But it is worrying. What are the symptoms of fungus or ringworm?
